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.

- 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.

- 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
