Fox Proframe with MIPS Matte Black: The Fox Proframe Helmet continues to be the lightest and most breathable full-face helmet Fox have ever created. Designed to meet the needs of all-mountain riders and enduro racers, it packs MIPS technology and a dual-density EPS liner into a superlight shell along with our patented, fully integrated chinbar. The Proframe Helmet has 15 intake and nine exhaust vents which provide exceptional airflow and breathability on both climbs and descents. Thanks to its fixed design, there's no need to stop, remove, and store the chinbar.
