Fox Proframe RS HelmetChanging the GameThe new Fox Proframe RS Helmet sets a new standard for lightweight breathability and function for a full-face helmet. With next-generation ventilation capability and decreased surface contact area, the Proframe RS elevates what you thought a full-face helmet was capable of. Included MIPS(TM) Integra technology reduces rotational forces during a crash without added bulk, while combining an EPP layer with the EPS layer for further protection. The sleek, race-ready lines of the Proframe RS are complimented by a three-position adjustable visor with goggle compatibility, with an included under-visor GoPro mount to let you capture all the action. The Proframe RS even features legendary BOA dial technology and replaceable cheek pads for a secure fit. Meanwhile, the Ionic+ anti-microbial inner liner helps to keep things fresh as you push your limits.
