Specifically designed to replace the marlin spike hitch, the Dutch buckle offers a lighter, faster, and safer method of connecting the whoopie sling to the tree straps. The buckle is completely adjustable, and you can slide it up or down to accommodate the tree size. Plus, its retention shock cord and latch method allow you to keep your tree straps neatly stowed away when not in use. Each 8-foot tree strap features a 3.5-inch loop, and can be cut shorter if necessary; just snip and melt the unlooped end to avoid fraying. The optional Dutch Clip replaces a carabiner for a quick connection and release, and can support up to 300 pounds.
