The FOX Mainframe combines style and safety in an affordable trail helmet. The proven MIPS™ impact protection system reduces rotational forces during an impact by absorbing and redirecting energies and forces that would otherwise be transmitted to the brain. It offers extended coverage for optimum safety. This extra-lightweight helmet features optimized ventilation with channeled, in-molded EPS for efficient cooling. The moisture-wicking liner is removable and machine washable. Weighing just 390 grams (size M), the helmet is made of 42% EPS, 15% PC, 14% PA, 11% PP, and 4% polyester. Ideal for mountain biking enthusiasts, the FOX Mainframe ensures you stay comfortable and protected on any trail.
