For most trail riders, I’d start with the Fox Racing Speedframe for its trail-focused coverage and practical feature set. The Smith Engage MIPS is another strong option for riders who prioritize a rotational impact system, while the Giro Fixture MIPS II offers a versatile alternative with broad size availability. The main tradeoffs are coverage, fit, ventilation, and whether you need a standard trail helmet or a full-face design. The lineup also includes simpler visor-equipped helmets for casual riding and a full-face option for riders seeking more facial coverage. Read on for how I’d match each pick to a riding style and what to check before choosing.

Key Takeaways
- Fox Racing Speedframe is my best overall pick for riders seeking a trail-specific balance of coverage and everyday usability.
- The Smith Engage MIPS and several Giro Fixture models include MIPS, giving protection features a more visible role in the comparison than basic visor-focused designs.
- The three Giro Fixture variants make fit and sizing worth checking closely: they differ by generation and size range, so the model name alone is not enough to choose.
- The Fly Racing Rayce is the lineup’s full-face option; its added facial coverage suits a different riding need from the open-face trail helmets.
- The Favoto, BATFOX, Exclusky, Bosoar, and ANY PASS options emphasize practical visor-equipped designs, but buyers should compare fit, coverage, and protection details rather than treating them as interchangeable.

More Details on Our Top Picks
Fox Racing Unisex Speedframe Mountain Bike Helmet
The Fox Racing Speedframe is the strongest fit here for riders who want an adjustable visor and a dialed fit for varied trail days. Its MIPS liner is designed to reduce rotational forces, while the 360-degree fit system helps secure the helmet without relying on a basic strap adjustment alone. Compared with the Smith Engage MIPS, the Speedframe offers a three-position, goggle-compatible visor and sunglass storage; the Smith instead lists Koroyd coverage and 20 fixed vents. The tradeoff is its open-face coverage, which leaves more of the face exposed than the Fly Racing Rayce full-face option elsewhere in the roundup. I’d choose it for trail versatility, but riders seeking full-face protection should look elsewhere.
Pros:- MIPS liner is designed to reduce rotational forces
- 360-degree dial fit system allows fit adjustment
- Removable, washable, moisture-wicking liner
- Three-position visor is goggle-compatible and includes sunglass storage
Cons:- Open-face design offers less face coverage than a full-face helmet
- The listed data does not specify weight or safety certifications
Best for: Trail and all-mountain riders who want MIPS, a secure dial fit, and a visor that accommodates goggles.
Not ideal for: Riders who want face coverage for downhill or highly technical riding; this open-face design leaves the face exposed.
- Brand:Fox Racing
- Model:Speedframe
- Age range:Adult
- Protection system:MIPS
- Fit system:360° Fit System
- Visor:One-hand adjustable, 3-position, goggle-compatible
- Liner:Removable, washable, moisture-wicking
- Venting:Channeled, in-molded EPS
Our verdict“Choose the Speedframe for adjustable, goggle-friendly trail versatility; choose the Fly Racing Rayce if you need full-face coverage.”
Smith Engage MIPS Adult Mountain Bike Helmet
The Smith Engage MIPS stands apart for combining MIPS and zonal Koroyd coverage with 20 fixed vents. That vent count may appeal to riders who run hot on sustained climbs, while the Ionic+ lining is intended to control odor between washes. Compared with the Fox Racing Speedframe, the Engage puts more of its listed emphasis on airflow and impact materials; Fox provides a three-position, goggle-compatible visor, while Smith’s visor has two positions. Fixed vents have a practical downside: they cannot be closed for cold or windy rides. The product data also gives no weight or detailed fit-system specifications, so riders seeking a clearly described dial fit may prefer Fox’s 360-degree system. This is the better match for ventilation-focused riders who value its listed protection features.
Pros:- Combines MIPS with zonal Koroyd coverage
- 20 fixed vents support continuous airflow
- Ionic+ lining is designed for odor control
- Complies with U.S. CPSC, CE EN 1078, and AS/NZS 2063 standards
Cons:- Fixed vents cannot be closed for cold-weather riding
- Two-position visor offers less adjustment than the Fox Speedframe’s three-position visor
- Product data does not specify weight or a named fit system
Best for: Riders who build up heat on climbs and want MIPS, zonal Koroyd coverage, and odor-control lining.
Not ideal for: Riders who often ride in cold weather or want vents they can close; all 20 vents are fixed.
- Brand:Smith
- Model:Engage MIPS
- Age range:Adult
- Gender:Unisex
- Safety certifications:U.S. CPSC, CE EN 1078, AS/NZS 2063
- Ventilation:20 fixed vents
- Lining:Ionic+ antimicrobial lining
- Visor:Adjustable, two positions
- Protection systems:MIPS and zonal Koroyd coverage
Our verdict“Pick the Engage for fixed-vent airflow and its listed MIPS and Koroyd features, provided you do not need to close the vents.”
Giro Fixture MIPS Bike Helmet, Matte Black/Grey, Universal Adult (54–61 cm)
The Giro Fixture MIPS is a straightforward choice for riders whose priority is an adjustable fit in the listed 54–61 cm range. Its Roc Loc Sport system gives a one-handed 7 cm adjustment range, and MIPS is designed to help reduce rotational forces. Reflective details may help with visibility when light hits them, but they are not a substitute for active lighting on dark rides. Compared with the closely related Giro Fixture MIPS II, this version has no listed ponytail compatibility; the II also specifies a fused outer shell and impact-absorbing foam. Neither listing gives a visor specification, so riders who want goggle-friendly adjustment should look to the Fox Speedframe. The Giro’s main limitation is sizing: the universal range may not suit heads outside its stated span or every head shape.
Pros:- Integrated MIPS system is designed to reduce rotational forces
- Roc Loc Sport offers one-handed adjustment across a 7 cm range
- Lightweight construction promotes airflow
- Reflective details can improve visibility when illuminated
Cons:- Listed universal sizing is limited to 54–61 cm
- Reflective details depend on an external light source
- No visor specification is provided
Best for: Adult riders with a 54–61 cm head circumference who want MIPS and one-handed fit adjustment.
Not ideal for: Riders outside the 54–61 cm range, those needing ponytail compatibility, or those who want a specified adjustable visor.
- Color:Matte Black/Grey
- Fit:Universal adult
- Size:54–61 cm
- Protection system:Integrated MIPS
- Fit system:Roc Loc Sport
- Fit adjustment range:7 cm
- Reflective details:Yes
Our verdict“Choose this Fixture for straightforward MIPS protection and an adjustable fit within 54–61 cm; consider the Fixture MIPS II if ponytail compatibility matters.”
Giro Fixture MIPS II Bike Helmet, Matte Dark Sage, Universal Adult (54–61 cm)
The Giro Fixture MIPS II earns a distinct spot for riders who need one-handed adjustment with ponytail compatibility. It pairs that fit system with integrated MIPS and a shell fused to impact-absorbing foam, giving the listing more construction detail than the original Fixture MIPS. Both Giro options cover the same 54–61 cm range and include reflective details, so the II is not a sizing upgrade. Compared with the Fox Racing Speedframe, it does not list a goggle-compatible adjustable visor or sunglass storage; its appeal is simpler fit flexibility. Reflective details only help when illuminated, and the universal fit may not accommodate every head shape. Riders whose heads fall outside the stated range should compare sizing before choosing either Giro.
Pros:- Integrated MIPS system is designed to reduce rotational forces
- Roc Loc Sport adjusts one-handed across a 7 cm range
- Fit system is compatible with ponytails
- Outer shell is fused to impact-absorbing foam
Cons:- Universal fit may not suit every head shape
- Reflective details need an external light source
- No adjustable visor specification is listed
Best for: Riders with a 54–61 cm head circumference who want one-handed adjustment and ponytail compatibility.
Not ideal for: Riders outside the listed size range or those who want a multi-position visor for goggles.
- Color:Matte Dark Sage
- Fit:Universal adult
- Size:54–61 cm
- Fit system:Roc Loc Sport
- Fit adjustment range:7 cm
- Protection system:Integrated MIPS
- Visibility:Reflective details
- Construction:Outer shell fused to impact-absorbing foam
Our verdict“Pick the Fixture MIPS II for ponytail-compatible adjustment in the 54–61 cm range, while the Fox Speedframe is the stronger listed option for goggle use.”
Favoto Adult Mountain Bike Helmet with Visor
The Favoto Adult Mountain Bike Helmet focuses on practical details: a magnetic buckle that can be operated with one hand, a rear cord for glasses, and a listed weight of 335 g. Those features make it a different sort of pick from the Smith Engage MIPS, whose listing emphasizes MIPS, Koroyd, and 20 vents but gives no weight or magnetic closure. Favoto lists a dual-shell PC exterior and 20 mm EPS foam, along with CPSC and CE standards. Its main weakness for a buying guide is the missing sizing and fit information, which makes it harder to judge whether it will sit securely on a particular rider. The product data also provides no MIPS or Koroyd specification, so riders prioritizing those named systems may prefer Smith or Fox.
Pros:- Magnetic buckle is designed for one-handed operation
- Rear elastic cord holds cycling glasses
- Listed weight is 335 g
- CPSC and CE standards are specified
Cons:- No sizing or fit-system details are provided
- No MIPS or Koroyd protection system is listed
- Impact-resistance comparisons are not provided in the product data
Best for: Commuters and trail riders who value a one-handed magnetic buckle, glasses storage, and a stated helmet weight.
Not ideal for: Riders who need detailed sizing guidance or specifically want a listed MIPS system or Koroyd coverage.
- Brand:Favoto
- Type:Mountain bike helmet
- Shell:Dual-shell PC
- Liner:20 mm EPS foam
- Weight:335 g (11.8 oz)
- Closure:Magnetic buckle
- Glasses holder:Rear elastic cord
- Standards:CPSC and CE
Our verdict“Choose Favoto for its magnetic buckle and glasses cord if the fit can be confirmed; choose the Smith Engage for explicitly listed MIPS and Koroyd features.”
BATFOX Mountain Bike Helmet with Visor for Men, Women, Adults & Youth
The BATFOX LA303 is a practical pick for riders who want full-coverage construction, a visor, and a dial fit without moving to a more feature-focused design. Its polycarbonate shell and EPS liner meet the listed CPSC, ASTM F1447, and CE standards, while 18 vented channels support airflow on casual trail rides. Compared with the Giro Fixture II MIPS, the BATFOX offers three defined size ranges and washable padding, while the Giro adds MIPS for riders prioritizing that impact-management system. The BATFOX’s large visor brings useful shade, but it is not adjustable, and the listed sizing may feel small on some head shapes. I’d choose it for straightforward fit adjustment and coverage, after measuring carefully; riders seeking MIPS should look elsewhere in this lineup.
Pros:- CPSC, ASTM F1447, and CE certifications are listed
- Polycarbonate shell with an EPS impact-absorbing liner
- Three size ranges and an adjustable dial fit system
- Removable, washable padding and 18 vented channels
Cons:- Sizing may run small on some head shapes
- The large visor is not adjustable
- No MIPS system is listed
Best for: Adult and youth recreational riders who want a dial-adjustable helmet with a large visor and washable padding.
Not ideal for: Riders who want MIPS or need an adjustable visor, and buyers whose head shape makes the listed size ranges difficult to fit.
- Model:LA303
- Safety certifications:CPSC, ASTM F1447, CE
- Shell:Polycarbonate
- Liner:EPS foam
- Ventilation:18 vents with internal channeling
- Sizes:M (54–58 cm), L (58–61 cm), XL (61–63 cm)
- Fit system:Adjustable dial
- Padding and visor:Removable, washable padding; large, non-adjustable visor
Our verdict“Choose the BATFOX LA303 for a visor-equipped, dial-fit helmet with three size ranges; choose the Giro Fixture II MIPS if MIPS is a priority.”
Exclusky Mountain Bike Helmet for Adults – Lightweight Adjustable MTB Cycling Helmet with Visor
The Exclusky suits riders splitting time between easy mountain-bike routes, commuting, road rides, and skateboarding. Its single-hand dial makes fit adjustments simple while riding, and the movable, removable visor gives more flexibility than the fixed visor on the BATFOX LA303. The PVC, PC, and EPS construction provides impact-absorbing materials, and breathable padding supports everyday comfort. Its broad use case is the main distinction here; the Giro Fixture II MIPS is a more trail-oriented choice for someone specifically seeking MIPS and in-mold construction. Exclusky’s tradeoffs are a visor attachment that may feel flimsy over time and a fit that may not suit larger heads. I’d favor it for general-purpose riding, but riders with a larger head or demanding trail use should compare fit and protection features carefully.
Pros:- Single-hand dial retention system
- Removable visor can move upward
- PVC, PC, and EPS construction
- Breathable inner padding for varied everyday rides
Cons:- Visor attachment may feel flimsy over time
- May not fit larger head sizes comfortably
- No MIPS system is listed
Best for: Adult riders who want one lightweight helmet for casual trails, commuting, road cycling, and skateboarding.
Not ideal for: Riders with larger head sizes or those seeking MIPS, a particularly robust visor mount, or a trail-focused feature set.
- Materials:PVC, PC, and EPS foam
- Fit system:Single-hand dial retention
- Visor:Large, reinforced, movable upward, and removable
- Gender:Unisex adult
- Intended uses:Mountain biking, road biking, commuting, and skateboarding
- Ventilation:Aerodynamic ventilation
- Padding:Breathable inner padding
Our verdict“Pick the Exclusky for adaptable everyday riding across several cycling styles, provided its fit works for your head and you do not need MIPS.”
Giro Fixture II MIPS Mountain Bike Helmet – Matte Titanium, Universal X-Large (58-65 cm)
The Fixture II MIPS stands out for riders who want MIPS and a stated 58–65 cm size range in a trail helmet with strong ventilation. Its integrated system is designed to redirect energy during certain impacts, a feature not listed for the BATFOX LA303 or Exclusky. Those alternatives offer visors and adjustable dial systems in their descriptions; the Giro instead pairs MIPS, in-mold construction, and 18 internally channeled vents. That makes it the clearest fit in this group for riders who prioritize MIPS and need an XL range, though the product data does not list a visor or a dial-fit system. Its one-year warranty is also a defined limitation. I’d choose it over the non-MIPS options for its stated protection technology, while riders who need visor adjustability may prefer the Fox Racing Speedframe.
Pros:- Integrated MIPS system designed to redirect energy during a crash
- Universal X-Large size range of 58–65 cm
- 18 vents with internal channeling
- Rugged in-mold construction
Cons:- Only a one-year warranty is listed
- No visor is listed in the product data
- No dial-fit system is specified
Best for: Trail riders seeking a MIPS-equipped helmet with a listed fit range extending to 65 cm.
Not ideal for: Riders who need a visor or a documented dial-adjustment system, or who prefer a longer warranty.
- Model number:7149901
- Size:Universal X-Large (58–65 cm)
- Safety technology:MIPS
- Construction:In-mold
- Ventilation:18 Wind Tunnel vents with internal channeling
- Color:Matte Titanium
- Warranty:1 year
- Brand:Giro
Our verdict“Choose the Giro Fixture II MIPS for its MIPS system, ventilation, and stated XL fit range; look to the Fox Racing Speedframe if visor adjustment matters more.”
BATFOX LA303 Mountain Bike Helmet with Visor for Adults and Youth
This BATFOX LA303 makes the most sense for riders who value easy-clean padding, broad size coverage, and a large visor in a straightforward helmet. Like the other BATFOX LA303 in this roundup, it lists a polycarbonate shell, EPS liner, 18 vents, and CPSC, ASTM F1447, and CE certifications. Its washable padding and chin pad suit frequent rides or shared household use. Compared with the Exclusky, it has more clearly specified certification and size ranges; the Exclusky’s visor, however, can move upward. The BATFOX’s visor is listed without adjustment, and the size ranges may run small for some head shapes. There is also no MIPS feature listed, unlike the Giro Fixture II MIPS. I’d pick this version for its stated care and sizing details, after checking measurements against its ranges.
Pros:- CPSC, ASTM F1447, and CE certifications are listed
- Removable, washable padding and chin pad
- Adjustable dial fit system across three size ranges
- 18 vents with internal channeling
Cons:- Listed sizing may run small for some head shapes
- No MIPS system is listed
- The visor is not described as adjustable
Best for: Families or regular riders who want specified sizing and padding they can remove and wash.
Not ideal for: Riders who need an adjustable visor, MIPS, or a fit outside the listed 54–63 cm ranges.
- Model:LA303
- Safety certifications:CPSC, ASTM F1447, CE
- Shell and liner:Polycarbonate shell with EPS foam liner
- Ventilation:18 vents with internal channeling
- Sizes:M (54–58 cm), L (58–61 cm), XL (61–63 cm)
- Fit system:Adjustable dial
- Padding:Removable and washable padding and chin pad
- Intended use:Mountain biking, trail, road, and commuting
Our verdict“Choose this BATFOX LA303 for washable padding and clearly stated size ranges, but consider the Giro Fixture II MIPS if you want MIPS.”
Fox Racing Speedframe Mountain Bike Helmet
The Fox Racing Speedframe is the most feature-led option here for riders who want MIPS, adjustable fit, and a visor that adapts to eyewear. Its 360° fit system and one-hand adjustable visor offer more on-ride tuning than the listed BATFOX helmets, whose visors are fixed, while the washable moisture-wicking liner adds a useful comfort detail. Channeled ventilation supports cooling, and the MIPS system is designed to help manage rotational forces. Compared with the Giro Fixture II MIPS, the Speedframe’s clearest advantage in the supplied details is its adjustable visor compatibility with sunglasses and goggles; the Giro specifies 18 vents and an XL size range. The Speedframe description does not give a size range or certification details, so buyers should verify fit and standards before choosing it. Its more adaptable setup is appealing, but those missing details limit direct comparison.
Pros:- MIPS system designed to help manage rotational forces
- 360° adjustable fit system
- One-hand adjustable visor compatible with sunglasses and goggles
- Removable, washable moisture-wicking liner
Cons:- The supplied product data does not state a size range
- The supplied product data does not list safety certifications
- No specific vent count is provided
Best for: Trail riders who wear sunglasses or goggles and want MIPS, adjustable fit, and visor positioning.
Not ideal for: Buyers who need a clearly stated head-size range or certification details before selecting a helmet.
- Protection:MIPS system
- Ventilation:Channeled, in-molded EPS
- Fit system:360° adjustable
- Liner:Removable, washable, moisture-wicking
- Visor:One-hand adjustable
- Eyewear compatibility:Compatible with sunglasses and goggles
Our verdict“Choose the Speedframe for eyewear-friendly visor adjustment and MIPS, after confirming its fit range and certification details.”
Bosoar GH-17 Mountain Bike Helmet for Adults & Teens
The Bosoar GH-17 suits riders who want to record a trail ride without adding a separate mount. Its built-in camera mount and 310 g weight give it a different focus from the more protective, downhill-oriented Fly Racing Rayce, which is a full-face helmet with downhill certification but weighs about 930 g. Bosoar’s open design and 15 vents are better suited to everyday trail riding, while the detachable visor also helps it adapt to commutes or road use. The tradeoff is a more limited fit range of 55–61 cm, so riders with larger heads should look elsewhere. It also has no listed manufacturer warranty, which makes its support less reassuring than the Favoto’s one-year coverage.
Pros:- Built-in action camera mount avoids the need for a separate attachment.
- At 310 g, it is lighter than the listed Favoto and ANY PASS helmets.
- Detachable visor supports both trail and road use.
- Fifteen vents and an anti-chafing chin pad support comfort on longer rides.
Cons:- No manufacturer warranty is listed.
- The stated fit range ends at 61 cm.
- Open-face coverage is not intended for the downhill use targeted by the Fly Racing Rayce.
Best for: Trail and commuting riders with 55–61 cm head sizes who want a lightweight helmet with a built-in camera mount.
Not ideal for: Downhill riders seeking full-face coverage or riders whose heads measure over 61 cm.
- Weight:310 g
- Head size:55–61 cm (21.6–24 in)
- Construction:In-mold PC shell with EPS foam
- Ventilation:15 vents
- Features:Built-in camera mount; detachable visor; adjustable fit
- Safety:CPSC compliant for bicycle helmets for riders age 5 and older
- Age range:Adults, youth, and teens 14+
- Warranty:None listed
Our verdict“Choose the Bosoar GH-17 for lightweight trail riding and onboard camera use if your head fits its 55–61 cm range.”
Fly Racing Rayce Full-Face Mountain Bike/BMX Helmet
For riders who need full-face coverage on gravity-focused trails, the Fly Racing Rayce is the clearest fit in this group. Its ASTM F1952-15 downhill certification, alongside CPSC 1203 and CE EN1078, sets it apart from open-face options such as the Bosoar GH-17, which is lighter and more versatile for ordinary trail rides but does not offer the Rayce’s full-face design. The Rayce weighs about 930 g in size M, so riders should expect more helmet mass than with the 310 g Bosoar. Intake and exhaust ports manage airflow, and the removable, washable liner helps with cleanup after hard rides. The D-ring strap is secure but slower to fasten than a quick-release closure, making it less convenient for frequent stops.
Pros:- ASTM F1952-15 downhill, CPSC 1203, and CE EN1078 certifications are listed.
- Full-face design suits gravity riding better than open-face picks such as the Bosoar GH-17.
- Removable, washable comfort liner and cheek pads simplify cleaning.
- Intake and exhaust ports support airflow and heat management.
Cons:- Approximately 930 g in size M, substantially heavier than the open-face helmets in this batch.
- D-ring closure takes longer to fasten than a quick-release buckle.
- Full-face coverage can be excessive for casual rides and routine commutes.
Best for: Adult downhill and gravity riders who want a full-face helmet with listed downhill certification.
Not ideal for: Trail commuters and riders seeking a lightweight open-face helmet for all-day pedaling.
- Weight:Approximately 930 g (size M)
- Shell:Poly-alloy
- Liner:EPS with removable, washable comfort liner and cheek pads
- Certifications:ASTM F1952-15 (Downhill), CPSC 1203, CE EN1078
- Ventilation:TFV system with intake and exhaust ports
- Closure:D-ring strap
- Visor:Adjustable with aluminum hardware
- Age range:Adult
Our verdict“Pick the Fly Racing Rayce for certified downhill use if you accept added weight and a slower D-ring closure.”
Favoto Mountain Bike Helmet for Adult Men & Women with Visor
The Favoto B025 puts everyday convenience at the center of its design. Its one-hand magnetic buckle is easier to operate with gloves than a conventional strap closure, while a rear elastic cord gives sunglasses a place to stay when they are off your face. Those details make it a more commute-friendly choice than the Bosoar GH-17, whose built-in camera mount better serves riders who want to record trail outings. Favoto’s 335 g weight is still manageable, and its removable visor adds flexibility. It lists CPSC, CE, and NTA 8776 standards, but the description does not give a vent count or detailed airflow system. Riders who prioritize ventilation details may prefer the 25-vent OutdoorMaster Gem, though that helmet has a more recreational, multi-sport focus.
Pros:- Magnetic buckle is designed for one-handed operation, including with gloves.
- Rear elastic cord holds sunglasses when they are not being worn.
- Removable visor supports varied riding conditions.
- Lists CPSC, CE, and NTA 8776 safety standards and a one-year warranty.
Cons:- No vent count or advanced ventilation system is specified.
- At 335 g, it is heavier than the 310 g Bosoar GH-17.
- Open-face coverage does not match the full-face design of the Fly Racing Rayce for downhill use.
Best for: Adult riders who wear gloves, switch between sunglasses and riding, and want an easy-to-operate buckle for everyday rides.
Not ideal for: Riders who want a specified high vent count or a helmet designed specifically for downhill riding.
- Weight:335 g (11.8 oz)
- Shell construction:Dual-layer PC shell
- Foam:20 mm high-density EPS
- Safety standards:CPSC, CE, NTA 8776
- Closure:One-hand magnetic buckle
- Included features:Removable visor; rear elastic sunglasses cord
- Age range:Adult
- Warranty:1 year
Our verdict“Choose the Favoto B025 for convenient daily rides if its easy magnetic buckle and sunglasses holder matter more than detailed ventilation specs.”
OutdoorMaster Gem Recreational MIPS Cycling Helmet
The OutdoorMaster Gem is the flexible pick for households or riders who move between cycling, skating, BMX, and MTB. Its MIPS safety system addresses rotational forces in certain impacts, and two removable liner thicknesses plus an adjustment dial give buyers more ways to tune fit than the fixed listed size range of the Bosoar GH-17. With 25 vents, it also offers more ventilation openings than the 15-vent Bosoar. The broader recreational focus is its limitation: the product data does not list downhill certification like the Fly Racing Rayce’s ASTM F1952-15 rating, so gravity riders seeking a helmet specified for that use should look to the Rayce. The two liner options may also fail to match every head shape, making fit checks especially important.
Pros:- MIPS system is designed to reduce harmful rotational forces in certain impacts.
- Two removable liner thicknesses and a dial allow fit adjustment.
- Twenty-five vents provide more ventilation openings than the Bosoar GH-17.
- Removable visor adds flexibility across recreational sports.
Cons:- No downhill certification is listed, unlike the Fly Racing Rayce.
- Recreational multi-sport design may not suit competitive gravity riding.
- The two liner thicknesses may not fit every head shape.
Best for: Youth and adult recreational riders who want one adjustable helmet for cycling, skating, BMX, and MTB.
Not ideal for: Competitive downhill riders needing listed ASTM F1952 certification or riders whose head shape does not suit either liner option.
- Safety system:MIPS
- Liners:Two removable liners: 0.23 in and 0.31 in thick
- Ventilation:25 vents
- Fit adjustment:Adjustment dial
- Visor:Removable
- Chin strap:Adjustable, skin-friendly
- Sports:Cycling, skating, BMX, MTB
- Age range:Youth and adult
Our verdict“Choose the OutdoorMaster Gem for adjustable recreational use across several sports, and look to the Rayce for specified downhill coverage.”
ANYPASS Adult Mountain Bike Helmet with Adjustable Fit and Removable Visor
The ANYPASS adult helmet keeps its feature set straightforward: an in-mold EPS and PC construction, 17 vents, an adjustable dial, and removable, washable padding. That makes it a practical routine-riding option for people who want to clean the contact padding without relying on a multi-sport liner system like the OutdoorMaster Gem’s two thickness choices. Its listed weight of 330 g sits between the lighter Bosoar GH-17 at 310 g and the Favoto B025 at 335 g. ANYPASS lists two size bands, M at 54–58 cm and L at 57–61 cm, which overlap but leave riders outside that span without a stated fit option. The provided details list CPSC compliance but no additional certification or warranty information, so buyers seeking those specifics may prefer another pick.
Pros:- Removable, washable padding supports regular cleaning.
- Adjustable dial and chin strap help tune the fit.
- Seventeen vents and 330 g weight suit routine riding.
- Removable visor can be taken off for a different riding setup.
Cons:- Only M (54–58 cm) and L (57–61 cm) sizes are listed.

Our verdict“Pick the ANYPASS for routine rides if your head fits its listed sizes and washable padding is a priority.”
How We Picked
I ranked these helmets around the needs that distinguish mountain biking from casual road or recreational cycling: trail coverage, fit adjustability, ventilation, visor usefulness, and stated protection features. I also considered how clearly each option serves a particular rider, including people who want a straightforward open-face helmet, a MIPS-equipped model, a broad size range, or full-face coverage. The ranking gives more weight to helmets with a clear trail-focused role and useful feature balance than to options whose listed strengths center mainly on a visor and general-purpose fit.
Within groups of similar helmets, I looked for meaningful differences rather than treating repeated model families as separate winners by default. That puts the Fox Speedframe and Smith Engage MIPS near the top for distinct trail-focused feature sets, while the Giro Fixture models remain compelling alternatives with model and size distinctions buyers should verify. More specialized or less fully specified options rank lower because their best use case is narrower or because the listed information leaves more for the buyer to confirm. I judge them on the features and intended use described, not on personal testing or claims about real-world impact performance.
Factors to Consider When Choosing Best Mountain Bike Helmets
Choosing a mountain bike helmet starts with matching its shape and coverage to your rides, then confirming it fits your head securely. These broader checks can prevent common buying mistakes that a feature list alone will not resolve.
Match coverage to the terrain you ride
Open-face helmets cover the top and back of the head while leaving the face open, which suits many cross-country, trail, and everyday rides. A full-face helmet adds coverage around the jaw and face, but that shape brings more bulk and can feel excessive on mellow routes. Think about the trails you ride most often, not only the most demanding day you might have once a year. A visor does not turn an open-face helmet into a full-face helmet, and it should not be treated as facial protection. If your riding changes between casual paths and technical descents, decide whether one helmet can serve both or whether the different needs justify separate helmets.
Fit and sizing matter more than a familiar model name
Measure your head where the helmet will sit and compare that measurement with the maker’s size range. A universal size label can cover a broad range, but head shape still affects comfort and stability. The helmet should sit level, feel secure when fastened, and stay in place when you move your head; a loose fit can compromise its intended performance. Check the adjustment system and strap placement before assuming a size will work. This is especially useful when comparing the Giro Fixture models, since their names and listed size ranges vary. If the maker offers a fit guide or return window, use it to resolve fit uncertainty before a ride.
Understand what a rotational impact system does and does not tell you
MIPS is a low-friction layer intended to allow some movement between the helmet and head during certain angled impacts. Its presence gives buyers a specific protection feature to compare, as seen in models such as the Smith Engage and Giro Fixture MIPS options. It does not make helmets interchangeable, guarantee a particular outcome, or replace checking the helmet’s certification and fit. A helmet without MIPS may still meet applicable safety standards, so weigh the complete design rather than one label. Look for the certification details relevant to where you ride and buy, since requirements can differ by market. Treat protection features as part of a decision that also includes fit and coverage.
Balance ventilation with the coverage you need
More vents can help heat escape on long climbs and warm-weather rides, but vent count by itself says little about comfort. A helmet’s shape, internal channels, hair, and how slowly you climb all affect airflow. Full-face designs generally cover more area, which changes how warm they may feel compared with an open-face trail helmet. Consider your usual climate and effort level rather than choosing by appearance alone. If you ride in variable weather, a helmet that works with your eyewear and any light layers you wear may matter as much as maximum airflow. Comfort helps you keep the helmet on for the whole ride.
Treat the visor as a practical fit and visibility feature
A visor can shade your eyes and help deflect branches or debris, but its usefulness depends on how it sits with your line of sight and eyewear. Some riders value an adjustable visor for changing light or riding positions, while others prefer a simpler fixed design. Check whether the visor is removable if you transport the helmet in a tight pack or want to use goggles. A visor should not block your view when you look ahead or force the helmet into an unstable position. For low-light rides, visibility and lighting matter more than a large brim. Choose the visor style around your routes and gear rather than assuming every trail helmet needs the same one.
Know when extra features or a second helmet are worth it
Paying more makes sense when the added feature solves a real need, such as a better fit range, a rotational impact system, or full-face coverage for a particular riding style. Extra adjusters or removable parts can also add setup and maintenance, so consider whether you will actually use them. A single open-face helmet may cover most trail and recreational rides, but riders who alternate between mellow routes and demanding downhill terrain may prefer a dedicated option for each. Check care instructions and inspect the shell, straps, and retention system regularly for wear. Replace a helmet after a significant impact or when its maker’s guidance calls for replacement. Prioritize a secure fit and appropriate coverage before cosmetic details.
Frequently Asked Questions
Should I choose a MIPS helmet over a helmet without MIPS?
MIPS adds a low-friction layer intended to allow movement during some angled impacts, which makes it a relevant feature when comparing these options. It does not replace a secure fit, suitable coverage, or checking the helmet’s safety certification. The Smith Engage and several Giro Fixture models list MIPS, while many visor-focused options in this lineup do not specify it in their names. Compare the complete helmet and confirm the exact model’s features before buying. Choose the MIPS option if that feature matters to you and the helmet fits well.
Is a full-face helmet worth choosing for regular trail rides?
A full-face helmet adds coverage around the face and jaw, which may suit riders who spend time on more demanding terrain or want that extra coverage for their riding style. It also covers more of the head and face than an open-face helmet, so it may feel warmer or bulkier on long climbs and casual routes. The Fly Racing Rayce is the only full-face option in this lineup, making it a distinct choice rather than a direct substitute for the open-face picks. Consider the trails you ride most often and how the helmet feels during sustained effort. If most rides are mellow, an open-face design may be easier to wear consistently.
How can I tell which Giro Fixture helmet is the right one for me?
Check the complete model name, generation, size range, and stated features instead of relying on “Fixture” alone. This roundup includes Fixture MIPS, Fixture MIPS II, and an X-Large MIPS II variant, so the differences affect both fit and model identity. Measure your head and compare it with the listed range for the exact option you plan to buy. Confirm whether the specific helmet includes MIPS, since product-family names can be easy to mix up. A correct fit should guide the choice between these closely related models.
Can I use a recreational cycling helmet for mountain biking?
Some recreational helmets can suit smoother paths and light riding, but mountain biking often calls for more rear coverage and a fit that stays stable over rough ground. The OutdoorMaster Gem is labeled recreational MIPS, so check its intended use and coverage against your routes before treating it as a trail helmet. Look at the certification, shell shape, retention system, and visor setup rather than the word “cycling” alone. For technical trails, a helmet designed for mountain biking may be a better match. Whatever the label, it should fit securely and meet the standards relevant to your location.
What should I do if a helmet feels comfortable but shifts when I move?
A helmet that shifts needs adjustment or a different size; comfort while sitting still is not enough. Set the retention system so the helmet stays level and snug, then adjust the straps so they hold without pinching. If it still moves after careful adjustment, the shell shape or size may not suit your head. Avoid relying on an overly tight chin strap to compensate for a loose fit around the head. Try another size or model and follow the maker’s fitting directions before riding.
Conclusion
For most trail riders, I recommend the Fox Racing Speedframe as the best overall choice in this lineup, with the Smith Engage MIPS as my pick for riders who want a clearly specified rotational impact system. The Giro Fixture MIPS II family is a useful alternative when its size range matches your head, and its several variants make checking the exact model especially important. For a simpler visor-equipped option, compare the Favoto, BATFOX, Exclusky, Bosoar, and ANY PASS models by fit and stated protection details; I would treat them as value-oriented candidates rather than assume they offer the same trail features. Beginners should start with a well-fitting open-face helmet that suits their usual routes, while riders seeking facial coverage should look at the Fly Racing Rayce full-face. Choose by coverage and fit first, then narrow the field by the features you will actually use.
