The Gatorback Carpenter’s belt is specially designed by those who have worked in the industry. The material is an ultra-durable 1250 Duratek Nylon and each bag and stress point is reinforced with bar-tack stitching and heavy duty rivets. From the carpentry and framing tools you use to the comfort and durability, all of this has been a factor in the design of this belt. With a patented design there is no other belt like this on the market!
