An ill fitting helmet is not only annoying to wear, it fails to protect your head like it should. Dial in the right fit every time with the K2 Route Helmet, complete with a 360 BOAR Dialed Fit System. This system is comfortable, easy to use and gives you the most precise fit you could ask for. Passive channel venting ensures that overheating won't happen, and earpads can be removed for warmer days. At 320 grams, this is the lightest snow specific helmet in the business, and a great choice for backcountry riders who carry the helmet on their pack much of the day.
