Giro Dime FS Youth/Junior Bike Helmet



The Dime FS is a kid-sized version of our rugged Quarter FS adult helmet so it has all of the same great features – an EPS liner for impact management, a tough outer shell, riveted webbing anchors and plush, sweat-absorbent pads. Another standout feature – Roc Loc Vert dial fit system allows you to easily adjust the helmet for a secure and stable fit. Dime FS is available in a bunch of great, kid-friendly colors too!
