Keep your sphere intact.
How much do we love the Giro Atmos Helmet? So much that it's been a permanent fixture in our cycling closets since it first appeared on the scene. Sure, we've flirted with some new, good-looking lids, but we've always come back to our true love, the Atmos.
The Atmos was the first helmet that ever looked amazing, while also saving our lives. It had tons of air channels, it was lightweight, and it was seriously durable -- this was still back when most helmets looked awful and weighed heavily on the head. And today, it still looks so cool, and works so well, that it's the most popular helmet that we've ever sold. The Atmos was so groundbreaking because it was the first helmet that made use of Giro's In-Mold Composite reinforcement. Through the use of this construction process, the outer shell has been permanently fused to the impact-absorbing, EPS foam liner. This process enhances the effectiveness of both parts. In fact, the fusion process actually reinforces the formerly vulnerable spots around the vents and ribs. It results in a lighter, more durable, and better-ventilated helmet. The Roll Cage internal reinforcement gives the added protection that you'll be glad to have next time someone takes you down in the final corner of a criterium.
The amazing comfort that the Atmos offers has been one of the main reasons for its longevity. Giro has taken over 20 years of helmet design to establish its proprietary, Super Fit Engineering. This means that Giro has created the helmet in three sizes based on 'human scale factors' data that have amassed throughout its history of handcrafting helmets. The helmets are intended to fit snugly and securely, while still accommodating the vast majority of head sizes.
Giro's development of its Roc Loc 5 Fit System makes those micro-adjustments possible. With the Roc Loc system, you can custom tune the fit tension as well as the fore-aft tilt of the helmet in seconds with one hand. Though other helmet manufacturers have similar adjustability options, none of them even come close to the weight savings that the Roc Loc system offers: it's almost 40% lighter than comparable systems.
Keeping your head cool during even the hottest, most critical road races is something that Giro has focused a great deal of attention on. Accordingly, its helmets are developed with a proprietary Wind Tunnel Ventilation System. Basically, it's an elaborate design that combines 26 vents in the shell with exhaust channels within the belly of the helmet leading to the rear. The effect is that the fresh, cool air from the front is strategically channeled around the head to help evaporate the sweat, then out the rear exhaust openings. It's a natural cooling system that you'll appreciate every ride.
The Giro Atmos Helmet is available in the sizes Small, Medium, and Large and in the colors Highlight Yellow/black, Matte Black/blue MC Hesheer, Matte Black/white, Matte Titantium, Matte White/silver, and Red/black. It also comes equipped with Giro's X-Static padding.
