Athlon

If your mountain bike riding style leans more towards a timing chip and a podium, Giro's Athlon is just what you need to keep your melon protected. The 23 Wind Tunnel vents keep the air flowing so you stay comfy all ride long. You'll love the removable visor that prevents rattling when you're tearing through terrain. Plus, the super-simple Roc Loc 4 adjustment system ensures a perfect fit every time.
