You bought your season pass for a reason. Now you need a helmet that feels as good on a storm-filled powder day as it does a bluebird groomer session or a backcountry mission. The women's Smith Liberty helmet brings the added energy absorption of Zonal KOROYD® and the advanced angled impact protection of Mips® to let you focus on ripping turns in the alpine and chasing powder stashes in the trees. Its hybrid shell design adds durability without weighing you down, while a plush sweat-wicking liner makes for all-conditions coziness. And because you love to ski or ride all day, the fit and vents are adjustable on the fly, so you can fine-tune the comfort.
