Our Standard Collection collars currently come in a one inch width with different widths coming in the near future. These collars are made with a black heavy Nylon fabric, 1.8 mm thick, with a tensile strength of 4,200 lbs. Strong enough for the toughest of dogs! They also come equipped with a heavy welded D-Ring, an extremely durable black buckle, and a heavy duty triglide slide.
