10 Best Full Face Mtb Helmet 2020 2026 in the United States

The Fly Racing Rayce MTB/BMX helmet is designed with safety in mind, featuring a durable polycarbonate-alloy shell and a multi-density EPS foam liner that helps absorb impact efficiently. This combination provides reliable protection during mountain biking or BMX riding. The shape is round, typical for motocross-style helmets, which often offer good coverage but could feel bulkier compared to more streamlined models.

Weighing 1.5 kilograms, it’s on the heavier side, so if you prefer extremely lightweight gear, this might feel a bit substantial over long rides. Comfort is well considered with padding inside. The helmet uses a simple buckle closure for the chin strap, which is secure and easy to adjust, fitting most adult head sizes (this one is large). It does not include a visor, which some riders look for to shield eyes from sun and debris.

The Fly Racing Rayce offers good protection and solid build quality for riders looking for a dependable full-face helmet, but those prioritizing lightweight design, ventilation, or a visor might want to explore other options.

The Fox Racing Proframe RS helmet is a solid choice for serious mountain bikers who want strong protection combined with comfort. Its Mips Integra Split system adds advanced impact protection by combining two types of foam liners to reduce rotational forces during crashes, which is a big plus for safety-conscious riders. The fit is excellent thanks to the BOA system, allowing easy, secure adjustment, while the Fidlock magnetic buckle simplifies putting the helmet on and taking it off. Ventilation is well thought out—the helmet has increased airflow and less surface contact, helping keep you cool on long rides. The Ionic+ liner and cheek pads are designed to manage odor and sweat, making it more comfortable over time.

The visor adjusts in three positions and fits with goggles, plus there's a removable GoPro mount under the visor, which is a nice bonus for riders wanting to capture footage. The helmet weighs about 3.3 pounds, which might feel a bit heavy compared to some competitors, especially for riders prioritizing lightweight gear. Also, while ventilation is better than older models, it may still feel warm on very hot days due to the full-face design. The helmet comes in a large size only, so fit options are limited unless other sizes are available separately.

This helmet offers a reliable, comfortable full-face option with advanced safety features and practical extras, making it suitable for adult riders, although those sensitive to weight may want to consider that factor.

The Smith Mainline helmet is designed for serious downhill and enduro mountain bikers who want strong protection without sacrificing comfort. It meets multiple safety standards, including downhill certification and MIPS technology, which helps reduce rotational impacts during crashes. Its Koroyd construction provides lightweight yet energy-absorbing protection, making it safer and less bulky compared to some other full-face helmets.

Ventilation is a highlight, with 21 fixed vents that keep air flowing to prevent overheating and reduce fogging of goggles or glasses. The helmet weighs about 770 grams, which is on the lighter side for full-face models, helping riders avoid neck fatigue on long rides. The adjustable visor offers three positions, letting you fine-tune glare protection or accommodate goggles. Comfort is addressed with multiple washable padding sets and liners, including cheek pads and neck rolls, so you can customize the fit to your head shape and preference. The chin strap uses a lightweight, low-profile buckle system that’s secure yet easy to operate.

One consideration is that its large size may not suit all riders, and while ventilation is excellent, those in extremely hot climates might still feel some heat buildup during intense rides. It is also a bit heavier than typical open-face helmets due to the full-face design, but that is expected for the added safety. The Smith Mainline serves as an excellent choice for mountain bikers needing a durable, well-ventilated helmet that prioritizes both protection and comfort during aggressive trail riding.
