Thank you for viewing our product! 【Moisture-Absorbing and Heat-Generating Flannel Fabric】 Uses moisture-absorbing and heat-generating material. It warms you by converting moisture released from your body into heat. The high-density flannel microfiber material has a smooth and soft feel. With fewer gaps between the fibers, warm air doesn't escape easily, providing excellent heat retention. 【Further Warmth with Binchotan Heat-Retaining Cotton】 Uses heat-retaining cotton with 30% Binchotan charcoal kneaded in. Warmer than ordinary cotton. With heat-retaining cotton, warmth is maintained for a long time! The back is a clean mesh fabric. While providing warmth, it also reduces night sweats and stuffiness. 【Anti-Static, Quilted Design, and Rubber Bands to Prevent Slipping】 Features anti-static function. Special quilted design for increased volume! Looks beautiful and feels comfortable to sleep on! Comes with rubber bands on all four corners to prevent slipping. Securely fixes to both futons and mattresses. Easy to install. 【Easy Care and Machine Washable】 Can be washed at home, so it's always clean.
