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.
