There is the gear you need and there is gear you love. The Smith Mission ski and snowboard helmet is both. Its lightweight design brings the latest safety innovations including MIPS™ and zonal Koroyd® for enhanced energy absorption in the event of a crash. Because you head to the mountain in all conditions, adjustable vents let you dial in the climate control. And because we live in a connected world, it has audio compatible ear pads. It's lined for instant comfort, and you can fine tune the fit with the adjustable dial.

Koroyd: Barrier for your brain. Koroyd’s network of life-protecting tubular cells crumple instantly and continuously, absorbing maximum force to control dangerous motion for any angle of impact, on any impact surface, minimizing energy transferred to your head. 

MIPS: The Mips® safety system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful forces that might otherwise be transferred to the user's head.
