Biothane leashes. The Biothane is a synthetic leather substitute. Soft to the touch, resistant to traction and wear, flexible. Does not absorb water. Does not require maintenance. Resistant to mildew, bacteria and odors. Washes easily with warm soapy water. The Biothane maintains its characteristics even at low temperatures. Mister Wolf uses original U.S.A Biothane. For my leashes the carabiners used are made of solid brass, HSSprenger steel and marine bronze
