If you want to rule the trail, you need Giro's Xar — the king of all-mountain lids. It boasts Giro's In-Mold construction for lightness and durability, while there are 17 large vents to keep you comfortable even when the mercury rises. You'll also dig how Giro's Roc Loc 5 retention system keeps the Xar in place on gnarly trails and bumpy descents, and how Giro's P.O.V. adjustable visor keeps the sun out of your eyes so you can concentrate on the trail ahead.
