Slippery when wet. Whatever your wet and messy style of play, our new Tough Rubber Bulldog can take what you give. This harness is made of black PVC weather resistant coating over black polyester web for strength. The straps are connected to Stainless Steel rings and buckles with 1/8” thick Neoprene rubber. The rivets used to assemble this harness are a nickel brass alloy with Stainless Steel washers for added strength.
