The Fox Racing Mainframe MIPS is an affordable MTB helmet with proven safety features and a comfortable style. This bike helmet is equipped with MIPS crash protection, a system which reduces rotational forces in the event of a fall by absorbing and redirecting the released energy and forces. This prevents these energy and forces from going directly to the brain. All in all, MIPS crash protection greatly reduces the chance of brain damage. The adjustment system is integrated with MIPS, resulting in a lower weight, and can be used to create a comfortable fit. For this MTB helmet, good ventilation has been a priority. Thus, there are integrated ventilation slots in the EPS material to ensure efficient cooling during your mountain bike rides. And if the helmet retains a somewhat sweaty smell, simply remove the moisture-regulating padding for a quick wash. The Fox Racing Mainframe MIPS guarantees great protection without scaring your wallet!
