This is such a great product. I never realized how much I dreaded lugging my laundry down the stairs until now. The backpack aspect is genius. Let alone that the PruPak can also be used as a cooler to carry my drinks to football games. Going to school in North Carolina, the heat does damage to my beverages, but not anymore. It is the perfect tailgate accessory due to the speaker that clips right on. Highly recommend!!!!
