Drawing a line that’s rarely inbounds. Descending at speeds that would give your underwriter pause. Pushing yourself in ways nature and gravity never intended. As long as you’re relentlessly pushing forward, we will too. When you stop, that’s when we’ll stop. We’re obsessing over your passion. Destroying more helmets in testing and development than some brands even create. We’re agonizing over vent sizes and inseam lengths. Pouring our years, our hearts, our sweat, into one insole, one goggle, one helmet at a time. Plainly said, being there when you need us most. Giro Helmet Sizing S M L XL Head Circumference (CM) 51-55cm 55-59cm 59-63cm 61-65cm Hardshell with In-Mold Hardbody Lower Wrap — The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight. Roc Loc 5 Fit System — The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the comfort and stability of helmets, Roc Loc 5 allows you to easily custom-tune the fit tension and fore-aft tilt of a helmet in seconds, using a single hand. And it's lighter than comparable systems too, making it the ultimate in skull-hugging luxury. Wind Tunnel Ventilation — Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider's head while forcing heat and stale air out. It's the most effective cooling system available, and a difference you can feel every time you ride.
