CarbonX Level 5 gloves are constructed genuine leather and backed with two top layers of flame-resistant CarbonX. Intense conditions demand increased protection so we incorporated a high-density accordion knuckle to shield your hands against impact hazards. The wide leather cuff allows for easy entry and a fit you can trust when the heat is on. Meets or exceeds SFI 3.3/5 & ARC 47.6 specifications.
