2021 Giro Quarter Bike Helmet - Adult

Giro Bicycle Helmet

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 Quarter is one of the lowest-profile helmets we've 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 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.
