You’ve probably noticed that ski helmets have become standard-issue gear for most skiers and snowboarders these days. When you consider that a blow to the head is one of the most dangerous injuries in sports, it’s easy to understand why. Built to provide a combination of impact protection and insulation from the cold, modern ski and snowboard helmets are lightweight, comfortable and designed to fit well with most protective eyewear. If you’re worried that your head might get too toasty, consider looking for a ski helmet or snowboard helmet with multiple air-channeling vents. Some models from brands like Bern, Giro and Smith even include adjustable vents for customized climate control.
