How to measure your size
Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.
Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
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 Giro have ever made, and it's also the lightest they'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.
