The Premium Marseillaise Belts allow the freediver to snug up the belt at the surface and forget it while going deep underwater. It is manufactured with a high-stretch rubber to keep your weights comfortably in proper position during ascents and descents. The high elastic properties of the belt will 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.
