Even on a mountain full of snow and ice, you still find yourself plagued with overheating while you ski. Enter the Salomon Allium 08 Custom Air Helmet and feel sweet relief from its incredible ventilation and fit customization. Whether the mountain gets pummeled by a Pacific puker or begins its annual April meltdown, the Allium's Thermo Control System lets you effectively regulate your head's temperature. A top grid vent expels warm vapors while you ski, and if you open or close the front and back vents, you can draw in cool air and let out hot air as needed.
