The Backsaver straps are designed to evenly balance the weight of a discgolf bacross across your shoulders. This can greatly affect your performance throughout the round. The Backsaver straps can be used in combination with Innova’s DISCarrier, Competition and Deluxe bags. The straps are also compatible with many of Innova’s older bags such as the Champion bag or the old Tour bag. Off course you can also use them for dogfrisbee.
