  • Portable shelter/garment
    Patent number: 5924132
    Abstract: Soldiers frequently form a make-shift shelter from a conventional poncho and the make-shift shelter is commonly called a "hootch" by soldiers. The term "hootch" is used here to refer to the portable shelter/garment, including its stuff sack, of this invention. The shelter/garment is made from pliable and waterproof fabric and is provided with snaps and loops along its edges and along its center line. The snaps and loops are used to hold the fabric in position after it has been folded to define a garment such as a poncho or a malke-shift shelter such as an A-frame. The snaps are arranged in such a way that two portable shelter/garments can be joined together to form a tent to shelter two persons. The portable shelter/garment of this invention was developed for use by the military and by hunters and others in need of a portable shelter while engaged in outdoor activities.
