It contains a moderate amount of warm air, providing high heat retention. Thin yet warm! It doesn't feel stiff. ❄️Anti-Static Processing Suppresses the generation of static electricity. Conductive fibers are mixed into the fabric, reducing static electricity and making it less likely for dust and pollen to cling. Deterioration due to washing, friction, or bending is not observed, so the antistatic effect lasts for a long time. ❄️Moisture-Absorbing and Heat-Generating Wadding Used Absorbs sweat during sleep and converts it into warmth, and it is also less prone to stuffiness, resulting in higher heat retention. Compared to conventional microfiber, the fiber density is higher, so the formation of pills and shedding of fibers during use is reduced. ❄️Washable at Home Can be washed at home. You can easily wash it in the washing machine repeatedly, so you can always keep it clean and comfortable. ⚠️There are wrinkles on the packaging, but it does not affect the box sheet itself.
