The DSL seat belt straps are fabricated in Australia from tough polyester. Leather ends sourced from the finest medium-weight stock are rivet-mounted to ensure reliability. Unlike synthetic straps, holes in this premium leather will not sag, twist, or crack. An adjustable tri-glide slides allows the strap to be lengthened and shortened easily. With a 2" width and premium, handmade material from Australia, this is an ideal option.
