Abstract: A backpack for preventing infections from surface and skin contact is disclosed. The backpack includes a sleeve, a pair of shoulder straps, and a protector including a top handle section connected with a pair of pulling straps, a middle padded section coupled to the top handle section, and a bottom section. Furthermore, the backpack includes a magnetic slide track fastener including a magnetic ring fixed at a bottom end of each of the pair of shoulder straps, and a magnetic pin fixed at a bottom end of each of the pair of pulling straps. When the magnetic pin is released from the magnetic ring via the downward sliding motion, the middle padded section protracts out of the sleeve. The magnetic pin is removably attached with the magnetic ring via the upward sliding motion of the magnetic pin to hold the middle padded section in a retracted position.
