A number of removable pockets are made so that ice packs or hot packs can be inserted into and removed from blankets or clothes or knee covers, and the pockets are locked with a jack or other locking means. In summer or winter, if you put an ice pack or a hot pack in a number of pockets formed on the knee cover of a blanket or clothes, lock the jacket, and sleep with the blanket on, you can sleep coolly or warmly.
