The Atomic Nomad with visor is a hybrid-shell ski helmet that combines an upper ABS hard shell for extra protection in the key impact zone, with an in-mold lower section to keep the weight down. And inside, Holo Core delivers up to 30% higher impact protection than industry standards require. For comfort, Live Fit pads mold to your head for an instant individual fit, while Active Aircon Venting, Atomic's most advanced cooling system, sucks hot air away from your head through the Holo Core.
