K2 Ski & Snowboard Helmet Size Guide
The table below gives the suggested head circumference for K2 Ski and Snowboard Helmets. The measurement is based on the broadest part of your head with the greatest circumference - usually just above your eyebrows.
In addition to the circumference, the shape of the head / helmet is key to getting a good fit. If you're shopping online and think you may be between two sizes then feel free to buy both sizes and return one - we have a very relaxed returns policy. Once you have your helmet and you have any queries feel free to give us a call any time to discuss the fit and if it's right for you.
Your ski / snowboard helmet should feel snug without being uncomfortable. There shouldn't be any notable 'pressure points' nor should the helmet move around freely when you move your head from side to side.
