The One Industries Gamma Raven Chrome Helmet gives you moto-rated head protection for your shred-related needs. Plenty of riders swear by DOT approved moto helmets, and that reason is that they’re certified for extremely high speed impacts. And that means that when you’re pushing it, either on the race track or at the bike park, your head enveloped in the highest possible degree of protection.

DOT certification exceeds the safety standards set forth for cycling helmets, and the Gamma passes those standards with room to spare. But its protection doesn’t mean much if you strain your neck railing a berm with the helmet on. That’s why One used a pre-preg fiberglass shell, which is not only strong, but lightweight. The shell is paired with a dual density EPS liner adding even more ability to slow impact forces.

Large flow-through ventilation ports help to keep your head from overheating. Admittedly, it’s not as heavily vented as some bicycle-specific offerings, but there’s a strong case to be made that the added protection more than makes up for it. And the removable head liner is easily washable, so any extra sweat you do expel won’t lead to a prematurely funky helmet.

The One Industries Gamma Raven Chrome Helmet is available in six sizes, from X-Small, to XX-Large, and in the color Chartreuse/black.
