Biothane is a near indestructible material which works very well for tracking and protection dogs, especially where they work in the open veld. It is soft and pliable, but is incredibly strong.
Grass and sticks do not stick to the material as it is smooth and firm. A wipe with a damp cloth and it is as new again.
The width is 19mm and colour a dark charcoal grey.
The biothane lead has a top quality trigger hook and a looped handle for comfort.
