The Fox Proframe Bike Helmet is the lightest and most breathable full-face helmet the brand has ever created. This is the original full-face trail helmet and is still the market leader. 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 Foxs patented, fully integrated chin bar. It has 15 intake and 9 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 chin bar. Conquer the mountain with the Fox Proframe Bike Helmet!
