The G5 RaceGrip gloves are designed for those who require the stringent SFI-3.3/5 requirements while giving you a lightweight feel with plenty of flexibility. Premium quality Nomex and premium leather are used along with a reinforced leather palm, leather reinforced knuckle pad, and adjustable Velcro wrist closure. The G5 gloves are limited with a flame-retardant fabric that wicks moisture away from your hands while maintaining that unique RaceGrip feel.
