The Ultra Marseillaise weight belt is a high-quality diving accessory made of rubber, designed with a focus on comfort and safety. With a thickness of 4 mm, this belt is constructed to withstand the rigors of underwater activities. Its standout feature is the stainless steel buckle in the Marseille style, known for its durability and ease of use. This buckle has a swiveling pin that engages with regularly spaced holes along the belt, ensuring a secure fit that can be quickly released in emergencies. The rubber material of the belt is specifically designed for elasticity, allowing it to automatically tighten when descending as the stomach compresses and the thickness of the wetsuit decreases. Thus, the belt remains snug against the diver's body throughout all phases of the dive, providing a consistent and reliable way to carry weights. The design of the Ultra Marseillaise belt prioritizes the safety and comfort of the diver, making it an essential tool for divers who demand the best in underwater gear.
