The all NEW OF77 helmet is based off of the very successful GM67. Features the all new 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.The 67s delivers a greater field of vision due to its large shield surface. Even with the removable jaw piece in place, the 67s field of vision is greater than most traditional full face helmets

 The best way to check sizing is to put the helmet on and see that the helmet feels snug equally all around your head. The helmet should not feel too tight or too loose at any particular point around your head.

If you can’t put it on, at all, then that’s obviously too tight. If you can get it on, but it hurts where it presses against your head, that’s also too tight. If it’s snug all around, too snug to chew gum, that’s about right. Don’t forget about that 15 percent to 20 percent break-in that will occur.
