The Giro Quarter Bike Helmet is the lowest profile helmet we've ever made, and it's also the lightest we've made with an ABS shell. All of the essentials are here a tough outer shell with impact absorbing EPS liner, riveted webbing anchors and plush, sweat absorbent pads that are easy to swap for dialing in the fit. A polyurethane coating helps to protect the EPS liner from daily wear and tear. Available in a bunch of great colors and three Super Fit sizes.
