The Ultra Marseillaise weight belt is a high-quality, rubber diving accessory designed with a focus on comfort and security. With a thickness of 4 mm, this belt is engineered to withstand the rigors of underwater activities. Its standout feature is the Marseille-style stainless steel buckle, which is known for its robustness and ease of use. This buckle has a pivoting pin that slots into regularly spaced holes along the belt, ensuring a secure fit that can be quickly released in an emergency. The belt’s rubber material is specially formulated for elasticity, allowing it to automatically tighten during a diver’s descent as abdominal compression occurs and the thickness of the diving suit decreases. This ensures that the belt remains snugly fitted to the diver’s body throughout all phases of the dive, providing a consistent and reliable means of carrying weights. The Ultra Marseillaise belt’s design prioritizes the diver’s safety and comfort, making it an essential tool for divers who demand the best in underwater gear.
