The Life Of A Skate-Style Dirt Helmet Is A Hard One. The Quarter™ Helmet Is Durable And Has A Polyurethane Bumper To Handle The Wear And Tear That Comes With Riding Trails Or The Skate Park. The essentials are here - an EPS liner for impact management, a tough outer shell, riveted webbing anchors and plush, sweat absorbent pads that are easy to swap for dialing in the fit. Another standout feature - the polyurethane coating helps to protect the EPS liner from daily wear and tear. Plus it's available in a bunch of great colors and three Super Fit sizes.
