Fizik Kassis MTB Trail + Light Helmet Built for the trail, designed to protect The Fizik Kassis is a robust half-shell helmet built for mountain biking and adventure trail riding. Extended coverage areas and a compact in-molded EPS/PC structure keep the helmet lightweight and agile while delivering serious protection in demanding off-road conditions. A polymeric reinforcement bridge distributes impact forces across the helmet, and MIPS Air Node technology is integrated directly into the padding for ultralight rotational impact protection. The breakaway adjustable peak visor shields against sun, mud, and trail debris, while rear vent channels double as a glasses garage. Fit is dialed in via a micrometric occipital dial with tilt adjustment and a dedicated crown adjustment feature.
