This versatile pocket holds up to 4lbs of weight, which is ideal for those traveling to warm water destinations or divers who add weight to tanks for trim purposes. With a small footprint of 3 inches x 4 inches (7.6cm x 10cm), you'll hardly know it's there. The 2-inch webbing loop and 2-inch stainless slide, keeps the pocket where you put it. The Travel Weight Pocket with Locking Attachment is ideal for use on basic style webbing harnesses, where there is nothing to keep a pocket from sliding around. Sold individually.
