The Fox Proframe, the original full-face helmet for the trail, is still the market-leading model. Designed to meet the needs of off-road and enduro riders, it combines MIPS technology and an inner shell of dual density EPS in a super-lightweight outer shell together with the patented, fully integrated chin bar. The Proframe is equipped with 15 air intakes and 9 outlets, providing outstanding air circulation and breathability for your climbs and descents. The integrated design means you no longer need to stop to remove and store the chin bar. The Proframe offers limitless riding pleasure. The lightest and most breathable MTB full-face helmet ever developed by Fox. In addition, the proven MIPS protection system reduces rotational movement by absorbing and dissipating energy and forces that would otherwise act on the brain. The integrated Fox chin guard is secured to the helmet with the patented system and meets ASTM testing standards. The highly breathable liner system is moisture wicking and has antimicrobial properties.
