The durable Oberon Cow Hide Leather Protector is worn over the higher voltage Rubber Electrically Insulating Gloves (Oberon RG Series). The Leather Protector is designed to ASTM F696 to protect from the rubber gloves against wear, puncture, and abrasion. The cowhide offers Long-wearing qualities that make them ideal for heavy wear. They are worn over the higher voltage rated rubber gloves (Class 1 & 2). For lower voltage rubber gloves, the Goat Skin leather gloves are thinner and more comfortable, easier to wear and work on fine tasks.
