Rely on a new level of protection with Proframe RS The Proframe RS Mash 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 Split protection system, which combines a dual density foam - for high and low speed impacts - and a low friction layer between the two layers designed to reduce rotational forces in a crash that would otherwise be 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 multi-sized cheek pads provide optimized comfort and fit. The updated BOA fit system offers micro-adjustability providing class-leading fit and security. The chinstrap utilizes a Fidlock magnetic closure system for easy-open and close, even with gloves. The 3-position adjustable visor with lock down screw is compatible with goggles. Those looking to capture every sweet run will appreciate the removable, under-visor GoPro mount on the Fox Proframe RS mountain bike helmet.
