Beyond the K2 Entity’s fun style and high performance, kids approve of the benefits of this ski helmet’s K2Dialed™ Fit System - intelligently designed to adjust ski season after ski season as your kids’ noggins continue to grow, or in future seasons for younger sibling hand-me-downs. New for this year is the LED KTail Light; a strobe light to keep track of your youngster in low visibility or when they start to become faster than you!
