The Classic 2.0 Snow is our signature brim helmet, a snowboard helmet first and certified for skiing too. Under the ABS shell, an EPS foam liner absorbs the force of an impact, the rear dial Fit System is anchored on both sides, and the grid fleece and mesh comfort liner comes out for washing. Sizes run Small to XL (52–67 cm). Sandbox helmets fit small, so size up if you wear a beanie or balaclava.
