  • Publication number: 20180116376
    Abstract: A backpack includes two sheets, two straps and a moisture-expelling apparatus. The sheets are connected to each other. The straps are connected to one of the second sheet. The moisture-expelling apparatus includes a permeable bag, a pump and a tube. The permeable bag is attached to the second sheet. The pump is inserted in the permeable bag. The pump can be squeezed to release air and can automatically expand to suck air when the squeezing stops. The tube is inserted in the permeable bag. The tube is connected to the pump so that air travels into the tube from the pump when the pump is squeezed and that air travels into the pump from the tube when the pump expands. The tube includes apertures via which air can enter and leave the tube.
