The RucPac Hardcase Backpack Conversion is a harness system that allows you to wear a wheeled hard case as a backpack to make it easier to carry over rough, rocky, or uneven terrain. It consists of a foam-padded back support, straps with a touch-fastener to adjust the height of the case on your back, and four weight-bearing quick release tension buckles. The fastener and buckles clasp onto the hard case in five places. For enhanced comfort, the Backpack Conversion evenly distributes the weight of the hard case across your back and shoulders using five key attachment points and the sternum strap. Attaching the Conversion Harness to your hard case can be done by securing the webbing through the top carry grip or through the trolley handle.

However it is attached, you can still access the inside of your case without having to remove the harness. There are two D-rings for attaching smaller accessories to your harness straps. If you need to remove the Backpack Converter, it folds compactly into your case.
