10 Models Reviewed in Depth
#1. POC Tectal Race MIPS Helmet
You’ll experience top-tier protection with the POC Tectal Race MIPS helmet, featuring an extended shell design for enhanced coverage at the temples and back of the head. The integrated MIPS system further boosts rotational impact protection, while the unique aramid bridges improve structural integrity and penetration resistance. Its 360° size adjustment system ensures a precise and secure fit for all-day comfort, and the wind-tunnel-tested ventilation keeps you cool on demanding trails. For maximum protection on demanding terrain, consider full face enduro helmets.
While the Tectal Race MIPS offers exceptional safety and coverage, some riders might find the fit slightly more snug than other brands, so trying it on is recommended. It’s an outstanding choice for enduro and all-mountain riders who demand the highest levels of protection and a secure fit, but if you prefer a very loose fit, consider sizing up.
Pros
- Superior MIPS and extended coverage
- Enhanced structural integrity
- Comfortable and secure fit
Cons
- Fit can be snug
- Higher price point
- Ventilation not class-leading
Specifications
#2. Fox Racing Speedframe Pro
You’ll be confident hitting the trails with the Fox Racing Speedframe Pro Helmet, boasting a top-tier Virginia Tech 5-Star safety rating. It incorporates a proven MIPS system, Varizorb dual-density EPS liner for optimized impact management, and the convenient Fidlock SNAP buckle for easy entry and exit. The 360° fit system ensures a perfect, secure fit, while the easily adjustable, multi-position visor adds versatility for different riding conditions.
While the Speedframe Pro offers exceptional features and safety, the comfort liner, though moisture-wicking, might not feel as plush as some premium competitors for extremely long endurance rides. It’s an outstanding choice for serious trail and enduro riders demanding the best in safety and features, but if maximum liner softness is your absolute priority, consider trying it on first.
Pros
- Top-tier safety rating
- Premium features like Fidlock
- Excellent impact protection
Cons
- Liner could be softer
- Higher price point
- Limited color options in pro version
Specifications
#3. Fox Racing Speedframe Helmet
You’ll appreciate the market-leading features of the Fox Racing Speedframe Helmet, including the Mips protection system designed to reduce rotational forces during impacts. Its optimized venting with channeled EPS provides efficient cooling, keeping you comfortable on demanding rides. The 360° Fit System allows you to dial in your perfect fit for enhanced security and comfort, while the one-hand-adjustable visor is compatible with sunglasses and goggles.
While the Speedframe offers excellent value and features, some riders might find the visor’s adjustment range slightly limited for certain goggle combinations. It’s a superb choice for aggressive trail riders seeking a blend of safety, comfort, and adjustability, but if you frequently use very specific goggle styles, double-check compatibility with the visor.
Pros
- Excellent MIPS safety
- Great cooling and ventilation
- Secure and adjustable fit
Cons
- Visor adjustment could be wider
- Slightly heavier than some
- Liner could be more plush
Specifications

With 20 vents and AirEvac ventilation, you can expect excellent airflow to keep you cool even during demanding climbs.
While the Engage MIPS offers outstanding protection and a dialed-in fit, some riders might find the integrated Koroyd material slightly less flexible than traditional EPS foam. It’s an excellent choice for serious trail and XC riders who prioritize safety and a customizable fit, but perhaps not the best option if you prefer a very minimalist, ultra-flexible helmet.
Pros
- Excellent MIPS and Koroyd protection
- Precise and comfortable BOA fit
- Great ventilation for hot rides

- Koroyd may feel stiff
- Limited visor adjustment
- Slightly heavier than some competitors
Specifications

It boasts complete Koroyd coverage for ventilated impact protection, alongside the MIPS Brain Protection System to mitigate rotational forces. The VaporFit dial adjustment system provides a precise 270-degree fit, and its seamless integration with Smith eyewear and goggles ensures fog-free lenses and convenient storage.
While the Session helmet offers fantastic comfort and integration, the visor’s three positions might feel slightly less versatile than a fully floating design for some users. It’s an excellent choice for riders who value comfort, seamless eyewear integration, and reliable protection on long, demanding rides, but if maximum visor adjustability is your top priority, explore other options.
Pros
- Excellent comfort and fit
- Seamless eyewear integration
- Effective MIPS and Koroyd protection
Cons
- Visor adjustment could be more flexible
- Higher price point
- Fewer reviews than some competitors

The Roc Loc Sport fit system offers easy, one-handed adjustment with a 7cm range, providing a secure and personalized fit.
While this helmet offers excellent value and features for its price point, some riders might find the ventilation less robust than higher-end models during extremely hot conditions. It’s a fantastic choice for recreational riders and those new to mountain biking seeking reliable protection and comfort without breaking the bank. If you’re new to the sport, consider these entry level mountain bike helmets.
Pros
- Integrated MIPS for safety
- Lightweight and well-ventilated

The adjustable dial fit system ensures a secure, personalized feel, while 21 vents with AirEvac ventilation maximize airflow to keep you cool on ascents and hot rides.
While the Engage MTB helmet provides excellent lightweight protection and cooling, the visor’s adjustment range is somewhat limited compared to other models. It’s a great choice for riders prioritizing a light feel and effective ventilation, especially for XC and trail riding, but if you need extensive visor adjustability for various conditions, you might look elsewhere.
Pros
- Extremely lightweight
- Excellent ventilation
- Secure adjustable fit
Cons

The MIPS integrated fit system contributes to a comfortable, seamless fit, making it a reliable choice for everyday trail riding.
While the Mainframe provides excellent core features for its price, some riders might desire more advanced adjustability or premium materials found in higher-end helmets. It’s a fantastic option for budget-conscious trail riders seeking solid protection and comfort, but if you’re looking for cutting-edge technology or a highly customizable fit, you might explore other models.
Pros
- Excellent value for MIPS
- Extended coverage for safety
- Good cooling performance
Cons
- Basic fit system
- Less premium materials
- Limited color options
Specifications

Multiple air vents are integrated to provide optimal ventilation and cooling on challenging descents.
While this helmet offers excellent protection and convenience features for aggressive riding, the ventilation might feel slightly less effective on very slow, technical climbs compared to more XC-focused helmets. It’s a solid choice for gravity riders and enduro enthusiasts prioritizing durability and ease of use, but perhaps consider a helmet with more aggressive venting if your riding is primarily slow-speed climbing.
Pros
- Durable ABS shell
- Convenient Fidlock buckle
- Comfortable, washable liner
Cons
- Ventilation may be limited
- Heavier than trail helmets
- No MIPS system
Specifications

Plus visor is fully adjustable, and the helmet features 16 Wind Tunnel vents with internal channeling for excellent cooling. Its rugged polycarbonate shell with an EPS liner, fully wrapped in a hardbody, offers durability and protection against the elements.
While the Montaro MIPS II offers solid protection and ventilation, the Roc Loc 5 Air Mips system might feel less refined or offer a slightly smaller adjustment range compared to some competitors. It’s a good option for technical trail riders seeking reliable MIPS protection and good airflow, but if a highly precise and extensive fit adjustment system is your top priority, you might want to compare it closely with other options.
Pros
- Integrated MIPS protection
- Good ventilation
- Adjustable visor
Cons
- Fit system could be more refined
- Fewer reviews than other models
- Visor adjustment range is limited
