Amumu stained glass guitar strap with premium leather ends and a widely adjustable length 37.5″ to 64″ to suit most players. Double layers of materials make the strap more durable and comfortable. The top layer is made from polyester with a stained glass jacquard pattern. The back layer is made from nylon.
