Abstract: A water-resistant combination blanket and coat is disclosed comprising a fabric sheet having a water-resistant outer surface. The fabric sheet may be spread on the ground as a blanket with the water-resistant outer surface down, thereby providing a place for a user to sit, even on wet, dirty, and/or muddy ground. Two points on the top edge of the fabric sheet may be reversibly connected to the right and left edges, thereby forming sleeves. A user may use the fabric sheet as a coat by placing his/her arms through the sleeves and wrapping the fabric sheet around him/herself. Reversibly connecting two points along the top edge of the fabric sheet to each other may further provide a hood while the fabric sheet is used as a coat. Alternatively, a detachable hood may be reversibly connected to the top edge of the fabric sheet while the fabric sheet is used as a coat. The detachable hood may comprise a pocket with two adjacent open sides.
