Working closely with professional cattle expert Kirk Stierwalt, we developed this innovative neck sweat system never before seen in the industry! This durable black harness leather shell comes with an SBR neoprene replaceable liner secured in place with heavy-duty hook and loop closures. SBR neoprene provides maximum heating potential for effective results. When it's time for a new liner, simply remove the old one and purchase a SBR neoprene or Flex Foam replacement liner and save the expense of buying an entirely new neck sweat. A chafing pad secures to the neck strap with the included screws for perfect positioning every time and a nosepiece with two hook and loop closure strips are reinforced with nylon for durability. Nickel plated hardware. Made by Weaver. Large size. Satisfaction Guaranteed
