Abstract: Rollers are fastened to a chassis which is removably held to a bottom of a backpack by hook and loop fasteners. The rollers are on legs which are rotatably mounted at one end so the rollers can be moved from a first, compact position to a second, expanded position to provide better stability to the backpack which rests on the rollers. Another hook and loop area on the backpack can be used to store the rollers and chassis when they are removed from the bottom of the backpack.
