Giro, Atomic, and K2 Helmet Sizing Chart

Determining your helmet size.

Ski and snowboard helmets gain in popularity every year and for good reasons! Helmets are lightweight, warm, functional, stylish and they protect your head! A ski or snowboard helmet is something you hope you never test to see if it works but glad you have it if an accident does happen.
  1. Use a soft measure tape for best results.
  2. Measure around your head, just above the eyebrows staying parallel to the floor.
  3. If you wear a headliner, measure with it on.
  4. If you're between sizes, go to the larger size.

How often should you replace your helmet?

Manufactures recommend you should replace your helmet every 5-7 years. Manufactures found with everyday use like when helmets travel in a bag, or hung on a back pack, get tossed on a table, thrown on the ground, and even put in storage, they found stress cracks. And anytime stress cracks are in a helmet, you need to replace it immediately because if you were to take a head blow, it wouldn't protect your head properly.
