evo.com | Fox Racing Bike Helmets > The Fox Racing Proframe RS Bike Helmet is better than ever thanks to a lighter, more breathable Race Spec (RS) construction and the all-new MIPS(TM) Integra Split technology! With two separate EPP and EPS liners, this mountain bike helmet offers even more rotational protection from fast and slow crashes, while still feeling light enough for a day of pedaling. Outfitted with a micro-adjustable BOA(R) 360deg fit system, the Proframe RS offers a snug fit while streamlining the helmet for better ventilation.
