The Speedframe 5050 Helmet is an open-face performance helmet that combines essential protection with Fox's iconic aggressive design DNA. It features MIPS(R) technology to keep you protected on the trail, optimized venting to keep you cool, and the 360deg Fit System for a perfectly dialed fit. The MIPS(R) added protection system has been proven to reduce rotational motion by absorbing and redirecting energies and forces otherwise transmitted to the brain. Optimized venting with channeled, in-molded EPS provides efficient cooling, while a removable, washable moisture-wicking liner keeps you comfortable. The 360deg Fit System allows you to dial in your perfect fit every ride by turning counterclockwise to loosen or clockwise to tighten. The back cradle features four points of adjustment to move the cradle up or down your head for the best fit possible. The one-hand-adjustable visor is compatible with sunglasses and goggles, and includes a sunglass-specific storage solution.
