This warm crew neck loungewear set is made with fluffy, soft double-sided fleece material. Both the outside and inside are fleece, which traps air and provides a gentle warmth that envelops your entire body from the moment you put it on. With a supremely comfortable feel, like being wrapped in a blanket, you can comfortably spend your time at home during the cold winter. The neckline features a classic crew neck design, which is soft against the skin and also durable, making it resistant to shape loss even after repeated washing. The cuffs and hem have a moderately snug elastic design to prevent cold air from entering and keep you warm. The bottoms also have a non-restrictive elastic waistband, providing a stress-free feel during sleep or relaxation. Available in kids' sizes, it's also appealing for matching outfits with your children. Matching outfits with the whole family will make your winter home time more enjoyable and perfect for creating heartwarming memories. With its high heat retention and excellent cold protection design, it is recommended for children who are concerned about catching a chill and those who are sensitive to the cold. Available in two colors: gray and pink. Sizes are 100cm, 110cm, 120cm, and 130cm. The material is polyester, and it is an imported product made in China.
