GOKUMIN Washable than a high heat soft flannel Comforter, Single, Winter, Moisture-absorbing, heat-generating [Warmer duvet]

[GOKUMIN's unique multi-layer structure makes it warmer than a duvet] We use high-density flannel that will make you feel warm from the moment you put it on the futon, and also combine it with highly insulating aluminum sheet and two carefully selected types of cotton. It shuts out the cold air from outside and traps the warmth inside the futon. [Moisture-wicking and heat-generating material allows you to stay comfortable all night without getting stuffy] Uses high-quality moisture-wicking and heat-generating material that increases the temperature by approximately 5℃ in about 6 minutes. It absorbs moisture generated while you sleep and converts it into heat. It suppresses stuffiness and discomfort, securely stores warm air, and maintains a comfortable sleep all night long. [Blissful feel that you won't want to let go once you touch it & washable] Made of smooth flannel fiber that is gentle on the skin, it will wrap you in fluffy and high-quality warmth. It is machine washable and has been treated with antibacterial and deodorizing treatment to keep it clean. Anti-static treatment reduces discomfort when touching the skin. [Quilt that fits tightly to the body and moderate volume] The quilt is ergonomically designed to fit tightly to the body without any gaps. Shuts out cold air and keeps you warmer. The filling is designed with just the right volume so you can use it without stress. We have thoroughly researched sleep, which takes up 1/3 of our lives, and have planned and developed it with the desire to create bedding that will give you the best night's sleep and even better when you wake up the next morning. We provide products that will satisfy you for a long time after you pick them up, with ``quality comparable to expensive bedding'' and ``comfort to sleep on.''
