Buckles and adjusters are produced by Woojin, one of the best plastic hardware manufacturer in the world. They are made of acetal which maintains long-lasting mechanical and shock resistance, even in extreme conditions. The plastic parts are rounded off and have no sharp edges.
Nylon webbing is made in the U.S.A. It's approximately 1.8 mm thick. It is a heavy-weight material and is stronger than polypropylene and polyester webbing. Nylon has a soft, lustrous feel. In addition, it is easy to care for as it is machine washable (we recommend you only dry it on low heat). Tensile Strength: 3,000 lbs.
All parts are sewn together with secure stitching and the overlapping parts, which have contact with the dog's fur or skin, are finished with a special stitching that avoids rubbing, particularly in short-haired dogs.
