Helmet Size Guide
How to Measure
Use a soft measuring tape and wrap it around the widest part of your head — typically about 1 inch (2.5 cm) above your eyebrows and ears. Keep the tape level around the back of your head. If you're between sizes, we recommend sizing down or choosing a helmet with an adjustment system. However, for all KASK helmets, we recommend sizing up by 2cm.
