Giro designed the G10 Helmet for riders who push their limits in wide-open free riding terrain. The wide-angle cut and gapless goggle fit insure you can see your takeoff, spot your landing, and spy everything in between with out any paranoia-inducing blind spots. In-mold construction fuses the exterior polycarbonate shell with the interior EPS liner for ultimate durability without compromising weight. 14 vents with on-the-fly adjustability combined with snap-fit, super-plush removable ear pads keep you cool, comfortable, and levelheaded regardless of the conditions. The G10 is Tune-Ups compatible.
