If you are looking for a solid and reliable ally that will accompany you season after season, Atomic's Nomad mountain helmet is an excellent choice. This is a new hybrid shell helmet that combines a rigid ABS upper shell for added protection in the crucial impact zone, with a molded lower section to reduce weight. And inside, the Holo Core provides up to 30% more impact protection than industry standards require. For added comfort, Live Fit earpads mold to the shape of your head for an instant individual fit, while Active Aircon ventilation, Atomic's most advanced cooling system, draws warm air from your head through the HoloCore.
