The Smith Liberty MIPS Helmet is tough, lightweight, and features adjustable ventilation—a handy package that gives you the freedom to explore the entire mountain, on- or off-piste. 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 this MIPS edition of the new Smith helmet features a Multi-directional Impact Protection System. MIPS uses a rotational liner that minimizes the force from angled impacts. 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. A soft, fuzzy lining ensures next to skin comfort, spin the fit dial for a slightly tighter or looser fit.
