Lightweight, next-level full-face helmet The Proframe RS Taunt 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.
