Now the Outfitter Sling is available in synthetic Biothane. What is Biothane? It is a super-tough nylon webbing encased in synthetic with a soft supple, grippy feel. It almost feels like leather, and performs very well hot, wet, or cold. Perfect for hostile environments. Available in Desert Tan color, which compliments modern camo patterns and won't stand out. Adjusts up to 43" in length, swivel to swivel. All Outfitter Slings use our infinitely adjustable buckle. Smarter because there are no holes and it adjusts quickly to any length. Rapid adjust, single loop design with a super fast positive locking mechanism. No moving parts, no knots to slip, no hooks to bend!
