Giro Atmos Racing Bike Helmet

The helmet's Wind Tunnel ventilation thrusts cool, fresh air over and around the rider's head.

Reinforcement and Fit
The Atmos also includes a roll-cage reinforcement--a tough web of DuPont nylon molded inside the helmet's EPS foam liner. This reinforcement provides an extra measure of strength and integrity that you'll never even notice--unless you need it. Finally, the Atmos helmet is engineered using Super Fit technology, making it so comfortable that it virtually disappears when you put it on. The proprietary three-size Super Fit system is based on "human scale factors" data and nearly 20 years of crafting helmets for the best riders in the world. The result is a helmet that fits 98 percent of the world's population, yet looks and feels like it was made just for you.

The Atmos helmet weighs only 275 grams and complies with U.S. Consumer Product Safety Commission's safety standards for bicycle helmets.

About Giro
Working late nights in his garage, designer/bike racer Jim Gentes created the first lightweight adult cycling helmet in 1985. Friends at NASA helped him tune the final helmet shape and vent placement, resulting in the Giro Prolight, a helmet that was better looking and better fitting than traditional designs yet still met the industry's toughest safety standards. Plus, it was half the weight of traditional helmets. Since then, Giro has advanced its helmets, many of which have set the standards for styling, function, and innovation for progressive, performance-oriented riders on dirt, pavement, and snow. Giro helmets are worn by millions of riders, cyclists, skiers, and snowboarders around the world: young bloods and old-timers; hardcores, heshers, and hipsters; rookies, experts, and a few regular Joes too--in fact, pretty much anyone that appreciates superior fit and function, cutting edge styling, and the very best ideas you get in a helmet. Giro is based in Scotts Valley, California.
