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 tune the final helmet shape and vent placement, and the result was the Giro Prolight, a helmet that was better looking than traditional designs while offering a superior fit and 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; hard-cores, heshers, and hipsters; rookies, experts, and a few regular Joes too--in fact, pretty musch anyone that appreciates superior fit and function, cutting edge styling, and the very best ideas you get in a helmet.
