It's a rope bag, a tarp, and a backpack. For effortless rope management, spread the tarp, flake the rope onto it, fold in the sides and roll it up into the pack like a burrito. Sling it onto your back and hike out to the trees. To deploy, unroll the tarp and haul up your rope free of tangles or debris from the ground. The pack is roomy at 16 inches tall and 10 inches in diameter. The tarp measures 40 by 55 inches. Compression straps, waist belt and padded shoulder straps are all adjustable, providing for a stable, comfortable load. There is even a large convenient pocket on the outside! Built to last, made of tough weather resistant nylon canvas and pack cloth.Climb anywhere!
