The Molchanovs SPORT Weight Belt is made of high-tech polymer, which provides the best resistance to wear-and-tear compared to silicone weight belts and has more elasticity compared to rubber weight belts. The fit of the belt on your hips is snug, but comfortable, and allows complete freedom of movement with a non-slippery surface. A high-quality stainless steel Marseille buckle allows for a safe quick-release in case of emergencies, and the absence of fasteners due to the buckle being directly integrated into the belt gives it improved durability. Pairs perfectly with our Lead Weights.
