Giro XAR Mountain Bike Helmet:
The Giro XAR Mountain Bike Helmet offers all the features you’ve come to expect from Giro’s top-level trail-riding helmets: P.O.V™ adjustable visor, in-mold composition with EPS foam and polycarbonate shell, Roll Cage™ reinforcement. But the XAR heralds a new era of performance, comfort and style. At the heart of this helmet you’ll find 17 Wind Tunnel™ vents as well as optimized internal channeling, and the visor is vented to increase airflow. Breathability on the Giro XAR Mountain Bike Helmet is incredible, there’s never been a lid this breathable on dirt, and even the padding is extraordinary thanks in part to X-Static fabric.
