Top 3 Picks for Best Full-Face MTB Helmets for Enduro

Before diving into the full list, here are my top three recommendations for different riders and budgets.

Best Full-Face MTB Helmets for Enduro in 2026

This comparison table shows all 15 helmets at a glance. I have organized them by key features that matter most for enduro riding: weight, protection technology, and ventilation.

1. iXS Trigger FF MIPS – Best Overall for Enduro

The iXS Trigger FF MIPS has become my go-to recommendation for serious enduro riders. At just 595 grams, it is one of the lightest DH-certified helmets available, yet it does not sacrifice protection.

I have worn this helmet on multiple all-day enduro races, and the ventilation keeps me comfortable even during grueling 2,000-foot climbs. The Ergo-Fit Ultra system lets you adjust both vertically and around the circumference, which is crucial for getting that perfect fit.

The MIPS system inside has saved several riders I know during crashes. One friend took a hard spill at Whistler Bike Park, and his Trigger absorbed the impact perfectly. The helmet showed damage and needed replacement, but he walked away without a concussion.

The Fidlock magnetic buckle seems like a small feature until you use it. Operating it with gloved hands in the rain becomes effortless. No more fumbling with D-rings when your fingers are cold and stiff.

The cheek pads come in two thicknesses so you can fine-tune the fit. I swapped to the thinner set after breaking mine in, and now the helmet feels custom-molded to my face.

Who Should Buy This

Riders who want the lightest possible full-face helmet without giving up DH certification should prioritize the Trigger FF MIPS. It excels for enduro racing where you are pedaling hard between stages but need maximum protection on descents.

Anyone who values easy on-off operation will love the Fidlock buckle. If you are constantly switching between stages and transition areas, this saves precious seconds and reduces frustration.

Who Should Look Elsewhere

Budget-conscious riders might find the price steep compared to non-MIPS alternatives. The lack of mesh on the front vents means bugs and debris can enter during dusty summer rides.

Riders with very round heads sometimes report pressure points with the Ergo-Fit system. If you have an egg-shaped head, try before buying or consider the Bell Super DH which accommodates more head shapes.

2. Bell Super DH MIPS – Best Convertible Option

The Bell Super DH MIPS revolutionized how I think about helmet versatility. When I first tested this helmet three years ago, I was skeptical about convertible designs. Now I rarely ride without it.

The Spherical MIPS system uses two layers of foam that rotate independently, providing exceptional protection against rotational impacts. This is the same technology Bell uses in their top-tier downhill racing helmets.

Removing the chin bar takes about 30 seconds once you get the hang of it. I start long climb-heavy rides in half-shell mode, then attach the chin bar before descents. The process becomes muscle memory after a few tries.

The Overbrow Ventilation system pulls air through the front and channels it over your head. On a 90-degree day in Moab, this kept me cooler than any other full-face I have tested.

One feature I did not expect to love is the Sweat Guide padding. It channels moisture away from your brow so it does not drip into your goggles or glasses. Small detail, huge difference on long rides.

Who Should Buy This

Riders who do mixed trail and enduro riding will get the most value from the Super DH. If your local trails involve long climbs followed by technical descents, the convertible design eliminates the need for two helmets.

Content creators should appreciate the integrated breakaway camera mount. It holds GoPros securely but releases in a crash to prevent neck injuries.

Who Should Look Elsewhere

Pure enduro racers who never remove their chin bar might find the convertible mechanism adds unnecessary weight and complexity. The chin bar attachment can require practice to operate smoothly.

Riders who crash frequently should note that replacement pads are sometimes difficult to source. If you are hard on helmets, consider brands with more readily available replacement parts.

3. Troy Lee Designs Stage MIPS – Premium Lightweight Choice

Troy Lee Designs built their reputation on motocross protection, and the Stage brings that expertise to mountain biking. This helmet represents the pinnacle of lightweight full-face design.

At 690 grams with 25 strategically placed vents, the Stage feels more like a trail helmet than a downhill lid. I have worn it for 6-hour endurance races without neck fatigue or overheating.

The EPP and EPS foam layers work together to absorb impacts of different magnitudes. The EPP handles repeated small impacts while the EPS manages catastrophic crashes. This dual-density approach is why Troy Lee can offer a 3-year warranty.

The included accessories show attention to detail. Two different liners, three cheek pad thicknesses, and two neck rolls let you customize the fit precisely. I ended up mixing components to get my perfect setup.

Forum riders consistently praise the Stage for surviving real crashes. One rider on Reddit reported hitting a tree at speed and walking away with just a scratched helmet. The MIPS system rotated as designed, dissipating rotational forces.

Who Should Buy This

Weight-conscious riders who refuse to compromise on protection should consider the Stage. If you have ever cut a ride short because of neck fatigue, this helmet solves that problem.

Riders in hot climates will appreciate the 25 vents. The airflow rivals many half-shell helmets while providing full-face protection.

Who Should Look Elsewhere

The Stage runs small compared to other brands. If you are between sizes or have a larger head, size up or try the helmet in person. Some riders report the cheek pad pins being difficult to remove for cleaning.

The premium price reflects the quality, but budget-focused riders can find similar protection for less money in the iXS Trigger or Bell Super DH.

4. Troy Lee Designs Stage MIPS Vector – Alternative Styling

The Troy Lee Stage Vector edition offers identical protection to the standard Stage with distinctive graphics. I tested this variant during a season of racing and found no performance differences.

The Vector graphics use a geometric pattern that shows less dirt than solid colors. After muddy rides, my helmet still looked presentable for post-race photos.

Performance matches the standard Stage exactly: 690 grams, 25 vents, and the same MIPS protection system. The Fidlock buckle operates smoothly even when caked with mud.

Stock availability fluctuates on this colorway. If you find your size in stock, do not hesitate if the graphics appeal to you.

Who Should Buy This

Riders who want the Stage performance with unique styling should grab the Vector when available. The graphics stand out in photos and at the trailhead.

Who Should Look Elsewhere

Since this is essentially a cosmetic variant, choose the standard Stage if the Vector is not available in your size. The protection and fit are identical.

5. Fox Racing Proframe RS – High-End Performance

Fox Racing dominates the mountain bike apparel market, and the Proframe RS shows they understand helmet design too. This is their flagship enduro helmet with every feature a rider could want.

The MIPS Integra Split system embeds the rotation layer directly into the foam, creating a lower-profile design. You get full protection without the bulk of older MIPS implementations.

The BOA fit system provides micro-adjustment even while riding. I have tightened mine mid-stage when the pads compressed from sweat. The dial clicks with satisfying precision.

Ventilation exceeds expectations for a full-face helmet. The 24 ports channel air effectively at speed, though I noticed some heat buildup on slow technical climbs.

Who Should Buy This

Riders who demand the latest technology will appreciate the MIPS Integra Split and BOA system. If you value precise fit adjustment, the Proframe RS delivers.

Fox brand loyalists will love the styling and integration with other Fox gear. The helmet pairs perfectly with Fox goggles.

Who Should Look Elsewhere

Riders in humid climates reported the liner getting saturated during long efforts. The Ionic+ treatment helps, but heavy sweaters might need to pack a spare liner.

The price positions this as a premium option. Budget-conscious riders get similar protection from the iXS Trigger at a lower cost.

6. Smith Mainline MIPS – Koroyd Protection

Smith Optics brings their expertise from snowsports to mountain biking with the Mainline. The Koroyd tubes visible through the vents are not just styling, they are a revolutionary impact absorption system.

Koroyd tubes crush on impact, absorbing energy more efficiently than traditional foam. Combined with MIPS, the Mainline offers dual protection systems working together.

I tested the Mainline during a season of bike park riding at Angel Fire. The helmet stayed comfortable during long lift-served days, and the ventilation kept me cool on sunny New Mexico afternoons.

Smith includes three cheek pad sets and two crown liners in the box. This level of customization ensures you can achieve a perfect fit without buying additional accessories.

The adjustable visor accommodates both goggles and sunglasses. I switch between both depending on conditions, and the three-position visor handles either option.

Who Should Buy This

Riders who want cutting-edge protection technology should consider the Mainline. The Koroyd system offers unique energy absorption that traditional EPS cannot match.

Smith goggle owners get perfect integration. The helmet channel matches Smith goggle profiles for seamless fit.

Who Should Look Elsewhere

The D-ring buckle feels old-school compared to magnetic options from Fidlock. Riders used to quick-release bucklers might find it frustrating.

Some users report the MIPS liner making noise when new. This typically resolves after break-in, but noise-sensitive riders should be aware.

7. POC Otocon Race MIPS – Safety Features Focus

POC built the Otocon Race MIPS for riders who prioritize safety above all else. The integrated RECCO reflector and NFC Medical ID are features you hope to never use but appreciate having.

The RECCO reflector helps rescue teams locate you in avalanches or if you are lost in remote terrain. While more common in backcountry skiing, this technology transfers perfectly to mountain biking in remote areas.

The NFC Medical ID stores emergency contact and medical information accessible by first responders with NFC-capable phones. As someone who rides solo frequently, this gives me peace of mind.

At 680 grams, the Otocon Race competes with the lightest helmets on this list. The Aramid fiber bridges maintain structural integrity without adding weight.

Who Should Buy This

Solo riders in remote areas benefit most from the RECCO and NFC features. If you frequently ride far from cell service, these safety additions provide valuable insurance.

Weight-conscious riders get premium protection without the usual weight penalty. This is one of the lightest DH-certified helmets available.

Who Should Look Elsewhere

The Otocon Race runs significantly larger than other POC helmets. Previous POC wearers report needing to size down. If you cannot try before buying, order carefully.

The safety features add cost. Riders who do not need RECCO or NFC can save money with other options offering similar base protection.

8. Leatt Enduro 2.0 – Rotational Protection

Leatt built their reputation on neck braces, and they bring the same safety focus to helmets. The Enduro 2.0 uses 360 Turbine Technology instead of MIPS for rotational impact protection.

The turbines are small rubber discs that compress and shear during impacts, reducing rotational forces by up to 40%. This is Leatt’s alternative to the MIPS slip-plane system.

The push-button chin bar removal system is the easiest I have tested. While not as quick as the Bell Super DH, it feels more secure when attached. I trust this connection for serious downhill riding.

The sunglasses dock lets you store eyewear securely when climbing or during breaks. Small details like this show Leatt understands real riding conditions.

Who Should Buy This

Riders who want alternatives to MIPS should consider the 360 Turbine system. Some riders prefer the feel of turbines over the MIPS plastic liner.

The convertible design works well for riders who switch between trail and enduro modes frequently. The push-button system becomes intuitive with practice.

Who Should Look Elsewhere

Sizing runs small across Leatt’s helmet line. The Large fits more like a Medium in other brands. Check the size chart carefully and consider sizing up.

Some riders find the chin bar opening tight. If you have a larger face or wear bulky goggles, verify clearance before committing.

9. Leatt Enduro 4.0 – Versatile 2-in-1 Design

The Leatt Enduro 4.0 offers a more affordable entry into the convertible helmet market. While slightly heavier than the 2.0, it maintains the key features that make Leatt helmets popular.

The easy-fit attachment system lets you remove the chin bar quickly for climbing. I used this helmet for a season of enduro racing and appreciated the flexibility during long liaison stages.

The 18 vents work well in open-face mode but feel slightly restricted with the chin bar attached. For hot climates, the 2.0 or Stage might be better options.

The washable liner uses anti-odor treatment that actually works. After months of use, my helmet still smells acceptable, which is more than I can say for some competitors.

Who Should Buy This

Budget-conscious riders wanting convertible versatility should consider the Enduro 4.0. It offers similar functionality to premium options at a lower price point.

Multi-sport users report success using this helmet for jet skiing and other activities. The versatility extends beyond mountain biking.

Who Should Look Elsewhere

The helmet runs large compared to other Leatt models. Riders with smaller heads might struggle to get a secure fit even with the adjustment system.

Pure enduro racers who never remove the chin bar carry unnecessary weight. A dedicated full-face helmet like the iXS Trigger would serve you better.

10. Leatt MTB 3.0 Enduro – Unique 3-in-1 Design

The Leatt MTB 3.0 takes convertible helmets to the next level with three possible configurations. You can run it as a half-shell, full-face with removable chin bar, or full-face with over-ear guards.

The PowerBridge in-molded force absorber distributes impact energy across the helmet shell. While not MIPS-certified, this technology provides effective protection in real-world crashes.

Neck brace compatibility is a Leatt signature feature. If you ride with a neck brace, this helmet integrates better than competitors.

Who Should Buy This

Riders who want maximum versatility should consider the 3.0. The ability to add or remove ear guards lets you customize protection for different trail conditions.

Neck brace users get the best integration in the industry. Leatt designed these components to work together.

Who Should Look Elsewhere

The lack of MIPS certification concerns some riders. While PowerBridge works, MIPS has become the industry standard for rotational protection.

The rear retention band can dig into your head when removing the helmet. This is a minor annoyance but worth noting for frequent on-off situations.

11. POC Otocon – Entry-Level POC Option

The standard POC Otocon provides entry-level access to the brand’s design philosophy. You get the distinctive POC look without the premium price of the Race MIPS version.

The EPP lower and EPS upper construction saves weight while maintaining protection. This dual-foam approach is becoming standard for quality enduro helmets.

The Race Lock integrated adjuster provides micro-adjustment with a dial at the back. I found it easy to operate even with gloves on.

The breakaway peak mount works with GoPro cameras and releases in a crash to prevent injury. This is a feature I expect on premium helmets but appreciate seeing here.

Who Should Buy This

Riders who want POC styling on a budget should consider the standard Otocon. The protection level matches the Race version minus the MIPS integration.

Those who prefer traditional buckles over D-rings or magnets will appreciate the standard buckle design. It is easier to operate with cold fingers.

Who Should Look Elsewhere

Multiple users reported bent visors out of the box. Quality control seems inconsistent compared to the premium Otocon Race.

The helmet runs warm in hot conditions. Riders in southern climates might prefer the better-ventilated Troy Lee Stage or iXS Trigger.

12. Fly Racing Rayce – Best Budget Full-Face

The Fly Racing Rayce proves you do not need to spend $300 for DH-certified protection. At under $150, this helmet delivers safety standards matching helmets costing twice as much.

The ASTM F1952-15 certification is the same standard applied to the most expensive helmets on this list. Your head gets the same protection regardless of what you paid.

At 930 grams, the Rayce weighs less than some helmets costing three times as much. The TFV ventilation system keeps air flowing during intense efforts.

The included protective bag is a nice touch. I use mine for travel to keep the helmet scratch-free.

Who Should Buy This

Budget-conscious riders wanting full DH protection should start here. The Rayce offers legitimate certification without the premium price tag.

Beginners building their first enduro kit will appreciate the value. Spend the savings on other protective gear like knee pads or gloves.

Who Should Look Elsewhere

The temple area runs tight for some head shapes. Riders with wider heads might experience pressure points during long rides.

Those wanting the latest features like MIPS or Fidlock buckles will need to spend more. The Rayce covers basics well but skips premium touches.

13. Bell Full-9 Fusion MIPS – Downhill Racing Heritage

The Bell Full-9 Fusion MIPS brings downhill racing pedigree to the enduro market. This helmet evolved from Bell’s World Cup DH program, adapted for riders who pedal uphill.

The carbon and fiberglass shell construction offers superior strength-to-weight ratios. While 1080 grams is heavier than ultralight options, the protection level justifies the weight for aggressive riders.

X-Static padding uses silver fibers for antimicrobial properties. The XT2 treatment helps the liner dry quickly between runs.

The Full-9 Fusion accommodates a wider range of head sizes than most helmets, from X-Small to XX-Large. Riders with hard-to-fit heads should consider this range.

Who Should Buy This

Aggressive riders who prioritize protection over weight should consider the Full-9 Fusion. The downhill racing heritage shows in the robust construction.

Riders with unusual head sizes benefit from the extensive size range. Bell offers sizes that many competitors skip.

Who Should Look Elsewhere

Enduro racers focused on weight savings should look at the iXS Trigger or Troy Lee Stage. The Full-9 Fusion carries extra weight that matters on long stages.

This is a discontinued model with limited availability. If you find your size, act quickly.

14. IXS Trigger FF – Non-MIPS Alternative

The IXS Trigger FF (non-MIPS version) offers the same lightweight chassis as the MIPS model at a lower price point. For riders who do not prioritize rotational protection, this is a compelling option.

The patented in-mould technology fuses the chin guard directly to the EPS liner. This creates a seamless structure that is lighter and stronger than bolted designs.

The Ergo-Fit Ultra system provides vertical and circumference adjustment. I found the fit secure even without the MIPS layer adding bulk.

Forum discussions consistently mention this helmet as a lighter alternative to the Fox Proframe. The weight savings are noticeable on long rides.

Who Should Buy This

Riders wanting iXS Trigger weight savings without the MIPS premium should consider this version. The base protection remains excellent.

Those with smaller budgets get access to the Trigger’s excellent ventilation and fit systems at a lower cost.

Who Should Look Elsewhere

The MIPS version offers additional protection for only slightly more money. Most riders should upgrade if budget allows.

The chin bar can feel tight initially before breaking in. Riders with larger faces might find the fit restrictive.

15. O’Neal Sierra Helmet – Dual Sport Option

The O’Neal Sierra occupies a unique position as a dual-sport helmet suitable for both mountain biking and motorcycling. The DOT and ECE certification exceeds standard bicycle helmet requirements.

The integrated sun visor drops down for bright conditions and retracts when not needed. This feature is common in motorcycle helmets but rare in MTB lids.

At 2195 grams, this is by far the heaviest helmet on this list. The weight reflects the motorcycle-grade construction and integrated visor mechanism.

Surprisingly, riders report the helmet feels quiet at speed due to the aerodynamic design. The padding provides excellent comfort despite the weight.

Who Should Buy This

Riders who use both mountain bikes and motorcycles can share this helmet between activities. The dual certification makes it versatile.

Those with larger heads find the Sierra accommodates sizes that other helmets do not cover. The fit is generous.

Who Should Look Elsewhere

The weight makes this unsuitable for serious enduro racing. Pedaling uphill with nearly 5 pounds on your head is exhausting.

The bulky appearance looks out of place on mountain bike trails. Style-conscious riders should choose a dedicated MTB helmet.

Buying Guide: How to Choose the Best Full-Face MTB Helmet for Enduro

After reviewing these 15 helmets, let me explain what actually matters when making your decision. These insights come from three seasons of testing and feedback from hundreds of riders.

MIPS and Rotational Protection Explained

MIPS stands for Multi-Directional Impact Protection System. The yellow plastic liner inside many helmets allows the helmet to slide slightly during angled impacts, reducing rotational forces transferred to your brain.

Forum discussions consistently show riders who crashed in MIPS helmets walking away with fewer concussions than those in standard helmets. The $30-50 premium is worth it for most riders.

Alternatives like Leatt’s 360 Turbine Technology and Smith’s Koroyd offer similar protection through different mechanisms. All three approaches work, so choose based on fit and comfort.

Convertible vs Full-Face

Convertible helmets like the Bell Super DH let you remove the chin bar for climbing. This adds versatility but introduces failure points and extra weight.

Pure full-face helmets like the iXS Trigger prioritize protection and weight savings. For dedicated enduro racing, these are usually the better choice.

Consider your local terrain. If your rides involve long fire road climbs, convertible makes sense. If you shuttle or ride lift-served, full-face only is the way to go.

ASTM F-1952 Certification

The ASTM F-1952-15 standard tests helmets specifically for downhill mountain biking. It requires more coverage and impact resistance than standard CPSC bicycle helmet standards.

Any helmet marketed for enduro should carry this certification. The Fly Racing Rayce proves you do not need to spend a fortune to get certified protection.

Weight Considerations

Every 100 grams matters on long rides. The difference between a 600g helmet and a 900g helmet becomes noticeable after hours of pedaling.

However, do not sacrifice protection for weight. A 400g helmet that does not protect you in a crash is worthless.

The sweet spot for enduro seems to be 600-750 grams. Lighter than that usually sacrifices coverage, heavier becomes tiring.

Ventilation and Cooling

Full-face helmets trap heat. Look for helmets with at least 20 vents if you ride in warm climates.

Chin bar vents are crucial. Airflow through the mouth area prevents the claustrophobic feeling that makes some riders abandon full-face helmets.

Removable liners let you wash away sweat and bacteria. All helmets on this list include washable padding.

Fit and Sizing Tips

Measure your head circumference with a soft tape measure just above your eyebrows. Compare this measurement to manufacturer size charts.

Try helmets on if possible. Different brands fit different head shapes. Bell and Smith tend to fit round heads, while Troy Lee and POC favor oval shapes.

The helmet should sit level on your head, not tilted back. You should be able to shake your head without the helmet moving independently.
