Pushing the edge, so you don't take up too much room in the wide-open freeriding terrain, the Giro G10 Helmet protects your noggin so you'll live for another day. With legs begging for mercy, this versatile design protects your melon with lightweight and durable in-mold construction, which bonds the EPS impact liner to the polycarbonate shell. Fourteen Supercool(TM) vents with on-the-fly adjustable Thermostat(TM) control help keep you cool as the trees and rock outcrops whiz by. This Helmet comes equipped with a removable ear flap for sensory enhancement, an adjustable chin strap with side-lock clip buckle, and Goggle Notch(TM) flush fit with the wide-angle face cut. Recommended for Freeriding, the G10 MX Helmet is compatible with the Giro TuneUps(TM) audio system for inspired plug in tunage.
