The Quarter is one of the lowest-profile helmets Giro have ever made, and it\\\'s also the lightest we\\\'ve made with an ABS shell. The essentials are here - an EPS liner for impact management, a tough outer shell, riveted webbing anchors and plush, sweat-absorbent pads for long-lasting comfort. Another standout feature - the Roc Loc Vert dial fit system allows you to easily adjust the helmet for a secure and stable fit.
