The FOX Mainframe combines style and safety in an affordable trail helmet. The proven MIPS™ impact protection system reduces rotational forces during a collision by absorbing and redirecting energies and forces that would otherwise be transmitted to the brain. With extended coverage for optimal safety, this ultra-light helmet features an optimized ventilation system with channeled, molded EPS for efficient cooling. The moisture-wicking inner lining is removable and machine washable. Weighing only 390 g (size M), the helmet is constructed from 42% EPS, 15% PC, 14% PA, 11% PP, and 4% polyester, ensuring durability and comfort on the trails.
