Giro Xen Mountain Helmet '10 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 this year are really something special. Sort of like art for your head.
