Whether we're shredding our favorite powder stash or biking a hidden trail, we stay safe with the K2 Stash Helmet. It's both snow- and bike-certified, and it's comfortable for multi-season wear, thanks to a new Convertible Full-Wrap liner that keeps the head and ears warm in winter and pops out to help us stay cool in summer. Even with the liner removed, we can use the 360 K2Dialed fit system to lock in the perfect fit with the twist of a dial. Passive ventilation channels pull cool air over the head to manage moisture and keep from overheating during spring slush sessions and bike park laps. The Magna-Snap goggle clip keeps our goggle strap in check so it doesn't slip when we take a spill.
