Why it matters

Biothane is a flexible core bonded with a waterproof coating, so the leash comes out of swamps and lakes dry, clean and smell-free, and outlasts leather. A swivel clip prevents twisting, and black electroplated hardware is non-reflective. Made in the USA in many colors, lengths and widths.
