GMax OF77 Helmet

The GMax OF77 Helmet is based off of the very successful GM67. It features the Spa Soft and CoolMax interior and multi-density cheek pads. The OF77 is like having two helmets in one. It offers the comfort of an open helmet, plus it quickly and easily converts to a full face helmet for those looking for increased protection and comfort with the installation of the optional jaw piece.

Features:

  • Lightweight DOT approved Thermo-Plastic Alloy shell
  • Anti-fog coated inner sun shield easily raised or lowered with a lever located on the exterior of the helmet
  • Cheek pads feature a multi-density foam construction creating a superior fit
  • Optional removable jaw piece (sold separately)
  • SPC top front vents/interior and styro designed for a controlled air flow
  • DEVS adjustable Dual Exhaust Venting System, top, side and rear venting reduces fogging and sweating by allowing hot air to escape from the mouth area and top of head.
  • Large eye port for improved peripheral and range of vision
  • Spa Soft, CoolMax comfort liner and cheek pads move the moisture away from your body and the fabric dried quickly
  • Removable/washable interior and adjustable cheek pads allow for more comfortable sizing
  • Deluxe ear pockets with built in space for speakers for use of communication systems
  • Soft padded chin strap
  • Helmet bag included
  • Optional LED brake light kit (sold separately)
