Giro Xen Mountain Bike Helmet

The Giro Xen Mountain Bike Helmet is the original and now iconic all mountain helmet. Its smooth low profile style hints at skate style influence, but its big vents, light weight, and expanded rear coverage define it as a high performance helmet for the modern mountain biker. And the colors and graphics make the Xen truly unique. In Mold Construction In mold construction fuses a tough polycarbonate outer shell with the helmet's impact absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In mold helmets can be lighter and cooler than traditional helmets. Wind Tunnel Ventilation Giro helmets are developed utilizing Giro's proprietary Wind TunnelTM ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate. Roc Loc 4 This system, found exclusively on the Xen, offers full adjustment of both fit tension and vertical position. Roc Loc 4 allows riders to easily customize fit, making the helmet more stable, especially on rough terrain. P.O.V. Visor Point Of View visors are anchored by a patented internal clutch mechanism that allows 15 degrees of tool free, on the fly vertical adjustment while preventing the visor from rattling and coming loose over rough and technical terrain. Roll Cage Roll Cage reinforcement is a tough web of DuPont R NylonR molded inside a helmet's EPS foam liner. It provides an extra measure of strength and integrity that you'll never notice...unless you need it.
