A new addition to the Smith line of adjustable helmets, the Liberty Helmet is tough, lightweight, and features adjustable ventilation that we love for all-day excursions with changing weather. It features a low-profile hybrid construction packed with impact-resistant foam and Smith's Koroyd filler, all of which help absorb the force from unfortunate spills. And thanks to an abundance of adjustable ventilation, the entire mountain is yours to explore-open them up to cool off on traverse or bootpack, then snap them shut when you're back on the wind-whipped ski lift.
