GMAX’s premium modular helmet adds a level of refinement to our helmet line up. With its “Dual Pivot” design, the GM-64 has a very low profile when the chin bar is in the open position making it feel lighter compared to traditional single pivot designs. A metal on metal locking system insures a positive lock for maximum security. The Coolmax interior keeps you comfortable and dry for those long days in the saddle.
DuPont Coolmax® interior keeps you dry and comfortable. Coolmax® wicks moisture away from your body and dries quickly
Removable, adjustable, washable Coolmax® interior allows for easy cleaning and custom fitting
Vents close to completely seal out the cold
GMAX D.E.V.S (dual exhaust venting system) top and rear vents reduce temperature by allowing hot air to escape from the top of the helmet
Adjustable mouth vent directs air upward across the inside the shield to help reduce fogging
Features a metal to metal jaw closure
Dual Pivot” modular jaw design allows the flip jaw to rotate further back and low on the crown of the helmet. This increases the line of sight when in the raised position and it lessens fatigue by maintaining an even distribution of weight
100% UV400 protection shield comes anti-scratch hard coated for a longer lasting clear view
Easy to use chin bar with push to open mechanism designed for use with gloves
Optional 3M reflective decals that can be placed on the helmet for added safety visibility
