FOX Speedframe Pro Defy Helmet

MTB bike helmet Fox Speedframe Pro Defy

The Speedframe Pro helmet was developed in collaboration with professional MTB riders and has earned a well-deserved 5-star rating in Virginia Tech's bike helmet reviews - and not by accident. This premium open MTB model offers top-of-the-line safety features to keep you protected on every trail ride.

At the top of the list is the MIPS Air Node protection system - a low-friction layer designed for lightweight, fully ventilated helmets that reduces rotational movement and deflects the force of impact away from your brain when you fall. Dual-layer Varizorb™ EPS further increases protection by evenly distributing impact energy over a larger surface area.

Thanks to the BOA® Fit System, you can adjust the helmet to the millimeter so it fits you perfectly every time. The Ionic+® liner is antimicrobial, eliminates odors, wicks moisture away from your head, and is also easy to remove and wash.

The visor can be easily adjusted with one hand and is compatible with both sunglasses and MX goggles. The helmet even has a special storage compartment for sunglasses under the visor.

MIPS - abbreviation for the protective system that minimises the impact of rotational forces. Developed after years of research, this system is a combination of inherent brain protection and the MIPS system, which can provide even better protection against oblique impacts to the head. The MIPS system mimics the brain protection method by providing the helmet with its own low-friction layer between the outer shell and the protective layer. In a MIPS helmet, another low-friction layer separates the shell and the protective layer, allowing the helmet to move with the head during an oblique impact. Traditional helmets are tested by impacting them perpendicularly on a flat surface. MIPS helmets are designed to respond to how some accidents occur, i.e., oblique impacts to the head.
