7. K2 Route Helmet
You’ve probably never spotted a bike helmet at the terrain park, and for good reason. Until now, sport-specific helmets were made to protect you in very limited, high-likelihood crashes. But K2’s Route is certified for streets and slopes, where, at 0.7 pounds, it’s the lightest snow sports helmet on the market. Removable earflaps and goggle clips help it make seasonal transitions, 59(!) vent holes allow it to breathe on sweaty summer rides and a slick Boa fit system snugs it down on almost any head. Now that’s using your noggin.
