Introducing the all-new Chamonix 3 helmet-the perfect choice for an all-road, everyday helmet. Featuring design elements pulled from our S-Works helmets, in addition to high-performance comfort and ventilation, the Chamonix is the perfect choice for your road, gravel, or commuting adventures. We designed the Chamonix helmet specifically for riders who live a bike-first lifestyle-looking for fun on every ride. Featuring Mips technology, a removable visor, and a sleek design all while earning the highest 5-Star Virginia TechA(R) Helmet Rating, you&&';;ll both look and feel good on the bike. The Chamonix delivers premier comfort, performance-driven ventilation, and S-Works inspired design language, all in an accessible package. Ventilation: Taken directly from our premium S-Works Evade 3 and S-Works Prevail 3, our 4D Brow Cooling leaves a gap between the helmet and forehead, drawing airflow into internal air channels-all so you can feel the rush of air through the helmet at slow speeds, keeping you plenty cool when the going gets hot. Personalization: The visor comes in handy for extra sunny days-but if that&&';;s not your thing, easily pop it off for a seamless look. Mips: The Chamonix comes equipped with Mips Essential Core-a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts. 5-Star Virginia TechA(R) Helmet Rating: The Chamonix earned the highest 5-Star Virginia TechA(R) Helmet Rating from the internationally renowned Virginia Polytechnic Institute and State University. For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. Headset SX fit system with micro-adjustable dial for easy, secure, and accurate fit. Tri-Fix web splitter for improved comfort and ease of strap adjustments. Mips Essential Core system for added rotational impact management. The Chamonix earned the highest 5-Star Virginia TechA(R) Helmet Rating from the internationally renowned Virginia Polytechnic Institute and State University.
