FOX SPEEDFRAME PRO DEFY HELMET

High-performance open trail helmet

Designed with input from our professional mountain bike athletes, the Speedframe Pro Defy helmet has earned the highest rating (5 stars) from the Virginia Tech Institute in the Bicycle Helmet Rating program. This high-performance open mountain bike helmet offers top-tier features to ensure maximum protection on the most challenging trails.

The MIPS® Air Node protection system is a low-friction insert designed to reduce rotational movements during impacts, dissipating forces that would otherwise be transmitted to the brain. The dual-density Varizorb™ EPS further enhances protection by distributing impact forces over a wider area. The BOA® Fit System allows for micro-adjustments to achieve a perfect fit. The removable and washable Ionic+® liner is antimicrobial, prevents odors, and wicks away sweat. The visor, adjustable with one hand, is compatible with both goggles and sunglasses, with a dedicated storage system for the latter.
