The Gmax F-88 full face motorcycle helmet was designed for riders who seek performance. The smooth shape of the helmet cuts through the wind like a knife through hot butter. A Spasoft coolmax interior soaks up sweat and cools the rider off in warm weather conditions. This lightweight poly alloy shell will keep you in the saddle longer thanks to reduced fatigue from the normal weight of helmets. The Gmax D.E.V.S. (dual exhaust venting system) pulls the hot air from the helmet to keep fresh cool air inside.
