Performance-focused open-face trail helmet. Designed with input from our pro mountain bike athletes, the Speedframe Pro Backfade Helmet has earned Virginia Tech’s best rating, 5 stars, in its Bicycle Helmet Ratings program for a reason. This top-tier open-face mountain bike helmet offers a market-leading feature set to keep you protected every time you hit the trails. Top of that list 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. 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.
