A washable sleeping bag that can be used as a cushion when stored. The ultra-fine fiber filling, which is suitable for washing, is resistant to repeated washing, and the quilting prevents unevenness and disorder. The double zipper can be opened and closed from the top and bottom, and when it's a little hot, you can adjust the temperature by opening the zipper on the leg side. If you connect the same type of sleeping bag and a zipper slider, you can use it widely as a double size.
