The Smith Variance Helmet is always a popular choice for freeskiers or anyone else looking for a cool style and ample ventilation. 18 different vents and the Low-Profile Regulator Adjustable Climate Control will keep fresh air moving through the helmet when you want it to, or you can close the vents should you start to get chilly. The AirEvac 2 Ventilation System uses vents across the top of your goggles and channels that run through the back of the helmet to keep air circulating inside your goggle frames to prevent fogging. Smith's Boa X Adjustable Fit System gives you that perfect fit with the crank of the dial on the back of the Variance. The Hybrid Shell Construction gives the Variance a very light on your head feeling, by weighing in at only 18.5 ounces. A Nanosilver Performance Lining does a fantastic job of wicking away moisture and keeping you cool on the mountain, regardless of the situation.
