The Cressie Marseillaise Rubber Weight Belt with Quick-Release Buckle for Free Diving and Spear Fishing allows the free diver to snug up the belt at the surface and forget it while going deep underwater. It's manufactured with a high-stretch rubber to keep your weights comfortably in proper position during ascents and descents. The high elastic properties allow this free diving belt to contract and compress with your body and wetsuit during your descent, and expand and stretch as your body and wetsuit expand during ascent, keeping your weight belt properly positioned around your hips. The Marseilles style buckle is made of heavy-duty, corrosion-resistant stainless steel, is attached to the belts with stainless steel rivets, and is designed for a quick release if necessary. Belts will accept hard block or soft pouch weight pockets. Mfrs. 2-year limited warranty.Manufacturer model #: TA626000.
