Abstract: A strapless horse blanket (10) made of stretch material has an exterior side (17), an interior side (19), a back portion (11), side portions (14), and a perimeter. The side portions (14) couple together at a front chest area (18), forming a neck opening (33) that has a firm material (24) or substantially inelastic material (31) attached around the circumference. The side portions (14) have front leg sleeve wraps (50) and rear leg sleeve wraps (52) that couple around each leg. The perimeter of the blanket, with the exception of the neck opening (33) has an elastic band (42) hidden in the blanket material. The back portion (11) has a back reinforcement strip (12) that extends from a neck area (16) to a tail end (60). High stress areas of the blanket at the sleeve wraps (50; 52) are supported by reinforcements (40). An embodiment with an optional strip of material with loop fastener (13) down the back portion (11) along with optional straps (15) facilitates attachment of a special over-blanket or sheet.
