9 Best Full Face Mountain Bike Helmets in 2026

At just under 750 grams with 27 vents, this helmet keeps your head cool without weighing you down on long climbs or rough descents. The MIPS system works to reduce rotational forces in certain impacts, while the EPP collarbone impact system and chinbar shock pads add an extra layer of protection where it matters most. It’s a well-rounded package for anyone who wants full-face security without feeling like they’re wearing a bucket.

The pivoting visor helps shield your eyes from sun, wind, and rain, though some riders may prefer a wider range of adjustment. The washable liner and included two sets of D-rings make it easy to dial in the fit and keep things fresh ride after ride. For the rider who wants proven safety features in a lightweight, well-ventilated shell, this is a smart pick.

At 690 grams, the Stage helmet is a lightweight full-face option that uses MIPS with dual-density EPP and EPS foam layers to manage different impact energies. The 25 vents pull air through continuously, so you stay cooler when the pace picks up. That makes it a smart fit for enduro racers or trail riders who want full-face security without the weight of a heavier shell.

The trade-off? The EPP foam layer is designed for low-speed impacts, while the EPS layer handles high-speed hits. For riders who pedal up to ride down, the Stage delivers a good balance of weight, ventilation, and coverage in this guide.

The Flex Spherical+MIPS system addresses high-speed, low-speed, and rotational impacts, making it a strong choice for riders who prioritize protection at speed. Its 19 vents and overbrow intake ports usher in cool air and push it through the air-channel matrix for full-head ventilation. The removable chin bar lets you switch between full-face and open-face use without tools, which suits trail riders who want adaptability.

For riders who document their descents, the integrated breakaway camera mount attaches without zip ties or tape and is engineered to separate upon impact, reducing injury risk. The Fidlock buckle on the Float Fit DH system allows one-handed fastening and release, so securing the helmet is quick even with gloves on. Reviewers note that the buckle’s magnetic closure aligns easily, making it simpler than traditional side-release buckles found on many full-face models.

The Mips Integra Split impact system combines an EPP liner with the EPS layer to reduce rotational forces in a crash. That gives enduro riders serious protection without the bulk of a downhill lid. Fox Racing designed the Proframe RS with increased ventilation and a smaller surface contact area to keep you cooler on long, punchy climbs, while the BOA fit system and Fidlock magnetic closure make adjustments and fastening quick even with gloves on. This is a helmet for riders who push hard on technical descents but still pedal to the top, and the removable GoPro mount under the visor means you can capture the action without extra straps.

For aggressive trail and enduro riders seeking full-face security with modern ventilation, the Proframe RS delivers where it counts. The BOA fit system provides a precise, secure fit that stays locked in on rough descents, while the Fidlock magnetic closure makes fastening and removal effortless even with gloves on. Increased ventilation and reduced surface contact area improve cooling during sustained climbs, and the Ionic+ liner and cheek pads actively manage odor while wicking sweat. A 3-position adjustable visor accommodates goggles, and a removable under-visor GoPro mount is included for capturing the ride.

The Spherical MIPS ball-and-socket design is the standout feature here, letting the outer liner rotate around the inner liner during a crash to redirect impact forces away from the brain. That means you get a layer of protection that doesn’t rely on hard plastic against your skin, which is a real comfort advantage on long descents. Giro pairs this with a Wind Tunnel venting system that pulls cool air through optimized front intake vents and pushes hot air out the rear exhaust, helping you stay cooler when you’re working hard. This helmet is built for riders who want top-tier rotational impact management and aren’t willing to compromise on ventilation.

The trade-off is weight. At 3.6 pounds, the Insurgent is noticeably heavier than something like the Fox Racing Proframe RS, which comes in at 3.3 pounds. That extra heft is felt on long climbs or when you’re carrying the helmet by its strap, but it’s a direct result of the dual-layer Spherical construction and the protection it provides. If your priority is the lightest possible full-face for all-day pedaling, the Proframe RS might be a better fit. But if you want the most advanced MIPS system available and are willing to accept a bit more weight for that peace of mind, the Insurgent is a compelling choice.

At roughly 930 grams for a medium, this full-face helmet delivers downhill protection without weighing you down on long park laps or race runs. The poly-alloy shell and EPS liner meet ASTM F1952-15, CPSC, and CE EN1078 standards, so you get certified coverage for gravity riding. Its TFV ventilation system uses multiple intake and exhaust ports to manage heat, and the removable washable liner makes post-ride cleanup simple.

Certified to ASTM F1952-15 downhill and CPSC 1203 standards, the Fly Racing Rayce MTB Helmet delivers full-face protection for gravity riding without the rotational impact systems found on some competitors. Its poly-alloy shell and EPS liner meet multiple safety certifications, so you can trust it for bike-park laps and downhill runs. The trade-off is no MIPS or Spherical tech, but the helmet focuses on certified downhill safety and a lightweight feel.

With 14 vents and a Flying Bridge Visor that channels air across the helmet, the Bell Sanction 2 keeps you cooler on the trail than many budget full-face designs. It carries both ASTM Downhill and BMX certifications, so it’s ready for aggressive riding without the premium price tag. The removable cheek pads make cleaning easy after muddy days, and the wide size range from XXS to XL means most riders can find a secure fit. This helmet offers proper full-face protection at a price that won’t break the bank.

The Bell Sanction 2 weighs 2.9 pounds, which is lighter than the Proframe RS from Fox Racing at 3.3 pounds, so it won’t weigh you down on long descents. It meets ASTM downhill and BMX safety standards, giving you certified protection for aggressive riding. With 14 vents and a Flying Bridge visor that improves airflow, this helmet keeps you cool even when you’re pushing hard.

At under 750 grams, this helmet is one of the lightest full-face options you’ll find, making it a natural pick for long climbs or hot trail days where every ounce counts. The 27 injection-molded vents push plenty of air through the shell, helping you stay cooler when the pace picks up. It’s built around an EPP collarbone impact system and chinbar shock pads, giving you solid protection without the bulk. Riders who prioritize ventilation and low weight over extra rotational safety layers will appreciate how easy it is to wear all afternoon.

The trade-off is that this model skips MIPS, which some riders prefer for added rotational impact management. If that’s a priority, the OutdoorMaster MIPS Full Face MTB Helmet includes that extra layer, though it weighs more at 2.9 pounds. For anyone who wants a breezy, featherweight full-face that still delivers strong core protection, the Grizzly balances weight and airflow effectively.

The Giro Coalition Spherical Helmet uses a ball-and-socket design powered by Mips that lets the outer liner rotate around the inner liner during a crash, redirecting impact forces away from your head. That’s the same core protection you’d find in top-tier spherical helmets, but here it’s paired with carefully placed front intake vents that pull cool air over your face and scalp. For riders who push hard on hot climbs or long descents, that airflow makes a real difference in comfort. The IONIC+ padding uses pure silver to naturally fight odor, so the helmet stays fresher ride after ride without needing constant washing.

At 1.8 pounds, the Giro Coalition Spherical Helmet is lighter than the Proframe RS from Fox Racing (3.3 pounds), making it a strong choice for riders who want full-face protection without excessive weight. The Spherical Technology with Mips allows the outer liner to rotate around the inner liner during a crash, redirecting impact forces for better safety. Optimized front intake vents are precisely placed to channel cool air over your head, which helps on hot days at the bike park. The emergency cheek-pad removal system lets you pull the pads out without disturbing your head or neck position, a thoughtful detail if you take a hard fall.
