Fox SPEEDFRAME PRO MIPS MTB Helmet DEFY AS Pewter

Performance-focused open-face trail helmet

Developed with insights from professional mountain bikers, the Speedframe Pro Defy Helmet has achieved a 5-star rating from Virginia Tech’s Bicycle Helmet Ratings. This premium open-face helmet features the Mips® Air Node system, which reduces rotational forces during impacts by redirecting energy away from the brain. Enhanced with dual-density Varizorb™ EPS foam, it disperses impact forces more effectively. The BOA® Fit System ensures precise, customizable adjustment, while the antimicrobial Ionic+® liner controls odor and wicks moisture, and is removable for easy cleaning. Its one-hand adjustable visor fits sunglasses or goggles, complemented by dedicated sunglass storage—ideal for serious trail riders seeking top-level protection and comfort.
