Designed to carry soft weights, the OMS weight belt is available in 5 sizes so you are assured a phenomenal fit. Constructed of 420 Denier nylon for durability and heavy-duty PVC coated nylon mesh for easy draining. The large flaps have Velcro® closures that cover the full width of the flap preventing the weights from accidentally slipping out. Each pocket holds up to 5 pounds and it closes using an anodized aluminum waist buckle that can be easily opened with one hand.
