Smith Hardline Carbon MIPS Helmet Three, two, one. Dropping. The Smith Hardline Carbon is feature-packed and designed for taking on the rowdiest lines on the planet. A fully constructed carbon weave shell with complete KOROYD(R) coverage delivers lightweight, energy-absorbing, ventilated impact protection, while Mips(R) reduces rotational forces from angled impacts. Built into the lower edge of the shell is a Smith-engineered collarbone impact protection zone - a genuine innovation designed to reduce the risk of helmet-to-collarbone contact in a crash. Quick-release cheek pads are ready for emergency removal, the adjustable breakaway visor locks high for under-visor POV camera mounting, and Air Evac(TM) ventilation integrates with Smith goggles for fog-free lenses. Three shell sizes with a comprehensive washable pad kit - two cheek pad sets, two crown liners, two neck rolls - mean you can dial in fit to the gram. Whether you're on the World Cup circuit or running weekend shuttles, the Hardline Carbon delivers.
