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. Available in a bunch of great colors and three Super Fit™ sizes.
Fit Kit Pad System
Our Fit Kit pads system allows you to adjust the fit of your helmet in just a few seconds, without any tools. Simply choose the best combination of fit pads from the assortment supplied with the helmet, and swap them out to optimize comfort and stability. It's fast, easy and allows you to customize the fit of the helmet without hassles.
Super Fit™ Engineering
Our proprietary Super Fit™ sizing system is based on “human scale factors” data and over 25 years of handcrafting helmets. By creating helmet molds in up to 4 adult sizes to match the human body’s form, our Super Fit™ sizes comfortably and securely fit riders, and feel like they are custom made just for you.
If you have an accident in any helmet it's a good idea to replace it. Giro offer the peace of mind that if you have an accident wearing one of their helmets they will replace it at a reduced price. Find out more here.
