Why Biothane Straps?
 Waterproof – won't absorb saliva, sweat, or rain
 Easy to clean – hose off or disinfect after each use
 No stretching – maintains consistent fit
 Odor-resistant – no barn or saliva smell absorption
 UV-resistant – won't degrade in sunlight
 Stronger than nylon or leather in wet conditions
