Riffe's Marseilles style weight belt is about as good as it gets when it comes to freediving and spearfishing weight belts. This weight belt is a flexible belt that stays in place while diving. While on deeper dives as your waist compresses, this flexibility allows for a snug fit ensuring the weight belt doesn't slip up across your chest. Heavy duty stainless steel roller buckle makes releasing the belt in case of an emergency a cinch. This belt is 57'' in length with 4mm thick rubber and1.75" width.
