The Proframe RS Helmet takes the lightweight breathability of the Proframe and takes it to the next level of safety and performance. Featuring the all-new MIPS Integra protection system, which combines an EPP liner with an EPS layer and is designed to reduce rotational forces in a crash otherwise transmitted to the brain. Designed to meet the needs of all-mountain riders and enduro racers, the increased ventilation and decreased surface contact of the helmet keep you cool on long rides, while the Ionic and anti-microbial liner and cheeks pads provide optimized comfort and fit. Fit is also assured care of the BOA fit system, offering class-leading fit and security, and the Fidlock magnetic closure system for easy-open and close use, even with gloves. The 3-position adjustable visor is compatible with goggles, and those looking to capture every sweet run will appreciate the removable, under-visor GoPro mount on the Fox Proframe RS mountain bike helmet.
