FOX Speedframe Pro Defy MIPS MTB Helmet Fluorescent Red
The new 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. Dual-density Varizorb EPS bumps up that impact protection further by spreading forces of impact across a wider area. The BOA Fit System allows for micro-adjustability for a perfect fit every time you ride. The Ionic+ liner is antimicrobial and manages odor while wicking moisture away from the head, and is easily removed and washed. The one-hand adjustable visor is compatible with either sunglasses or goggles and the helmet features a sunglass-specific storage solution. If you’re looking for a performance-minded trail helmet, congratulations—you just found your new lid.
