The outer shell of the full leather welding gloves is made of shoulder split cowhide, with the features of abrasion, cut, flame and heat resistance, equalizing material, medium soft, and cotton lining which is more sweat absorbent, slide resistant and strong grip. They are all sewn with high strength, high heat resistant KEVLAR thread, applicable to cut, weld and handle and so on. The wing thumb construction allows the thumb to perform naturally, such as holding welding objects.
