Fox Racing Mainframe Trvrs MIPS Adult MTB Helmets (Brand New)
STYLISH, AFFORDABLE, MIPS TRAIL HELMET.
The Mainframe MIPS Helmet gives you exactly what you're looking for in an affordable helmet: proven safety features combined with easy trail steez. Featuring extended coverage to protect more of your noggin', the proven MIPS impact protection will keep your brain safe in the event of a crash by absorbing and redirecting energies and forces that could otherwise damage it.
