Designed to suit the needs of professionals and enthusiasts alike, Fox Racing Speedframe Pro Mountain helmets offer users a top-tier open-face mountain bike helmet option with a host of useful features that will keep your ride as smooth as it is safe. Integrated within Fox Racing Speedframe Pro helmets is the MIPS Air Node protection system, a Low Friction Layer for fully ventilated lightweight helmets designed to reduce rotational motion and redirect forces away from your brain should you crash. Users are able to dial in the fit of Speedframe Pro using BOA Fit, a dial retention system that allows for micro-adjustability around the head, leaving users with their desired fit in seconds. Inside Speedframe Pro helmets is the Ionic+ liner, a moisture-wicking foam pad network that has been treated with an antimicrobe treatment for defense against lingering smells. A one-hand adjustable visor is compatible with either sunglasses or goggles and the helmet features a sunglass-specific storage solution.
