Giro Athlon MTB Helmet

When you want to thrash some trails or attack some singletrack, Giro's Athlon is just what you need to keep your melon protected. The 23 vents and Giro's wind tunnel ventilation system keeps 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.

The Roc Loc 4 tension mechanism has three adjustments to enhance helmet stability without sacrificing ventilation; it’s ponytail compatible, too.
