TUFF Olympic Lifting Straps are made with heavy duty stitching to strengthen the strap and make it last longer than the competition. The increased contact with the bar helps to improve grip strength, and it does so without compromising any feel for the bar. These are designed in such a way that the bar can be released quickly during a lift to help prevent possible injury. These are rated at a maximum weight of 300 lbs. If you are looking for a lifting strap that supports more weight, please check out our TUFF Figure 8 Straps, TUFF Max lifting straps or our TUFF v2 Lifting Straps. Sold in pairs, with a single closed loop at one end and a carefully sewn off edge at the other to prevent fraying.
