The Smith Allure Snow Helmet is one of the lightest options on the market at just 12 ounces. But that doesn't mean it's light on features or safety. The Lifestyle Fit System, which automatically adjusts to the size and shape of your head every time you put the helmet on, also allows you to wear a beanie and goggles under the helmet. In addition to packing extra warmth in this lets you go with a competition-ready look, complete with removable earpads and goggle lock. It's entirely certified for safety too, that is the purpose of a helmet after all.
