The K2 Thrive Helmet equips you with everything you need to safely and soundly shred from first chair to last. The helmet's hardshell construction is built to firmly withstand impacts to all regions of the head, and uses an EPS foam to keep it lightweight. A well-fitting helmet is an effective helmet, and the K2 Dialed Fit System uses an adjustable three-point interface to find a fit that is just right for you at just the twist of a dial. The Passive Channel Venting also direct air flow to remove moisture and excess heat for a more dry, comfortable noggin. Don't just survive a day on the slopes, but flourish with the K2 Thrive Helmet.
