There are plenty of full face helmets on the market today, but few cycling-specific full face helmets can claim to be DOT certified -- and be as light as the One Industries Atom Helmet. One Industries has stepped into the mountain bike game with extensive moto experience, and because of that know how, they're able to offer one of the highest-safety rated helmets available.

DOT certification exceeds the safety standards set forth for cycling helmets, and the Atom easily passes those standards. You'd be hard pressed to find another mountain bike helmet that can claim that. But, while safety first is the name of the game, helmet weight is an equally important factor.

You don't want to blow up your neck muscles midway through a day of lift riding due to a weighty helmet. The Atom features a lightweight polycarbonate shell that's reinforced with a alloy crown for superior impact absorption and an excellent strength to weight ratio. The shell is paired with a dual density EPS liner adding even more ability to slow impact forces.

The EPS liner and shell have flow-through ventilation with large intake and exhaust ports to keep your noggin cool. But no matter how much air flow you can push through a helmet you're still going to work up a sweat. So, to keep the Atom from becoming a stink bomb, the moisture-wicking Nylex comfort liner is removable and easily cleaned.

The One Industries Atom Helmet comes in Rockstar Black, Bolt Black/Orange, Bolt Black/Gray, Bolt Red/Orange, Beemer Black, Beemer White, Cypher Black/Red and sizes X-Small through X-Large.

Simply Fantastic

  • Familiarity: I've used it several times

This is my first full face MTB helmet and it has not disappointed. Not overly heavy and after a full day of use your head and neck isn't stiff. As for protection, top notch. Besides being DOT certified, it just feels well built and provides that level of confidence when riding park. I'm extremely happy with my purchase, thank you Back Country for a great helmet at a great price.
