Material: 100% pure, natural, and breathable cotton of excellent quality that allows the skin to breathe. It distributes body heat well and helps alleviate the feeling of heat in summer. It's a generally very soft fabric that is comfortable against the skin. Why Choose: Cotton is hypoallergenic, making it a better choice for women with sensitive skin. It absorbs moisture very well, helping to reduce sweat and odor. Function: Since it's pure cotton, some shrinkage is normal after the first wash. This loss is physiological in nature and actually confirms that the product is made with pure cotton fabric containing no other synthetic fibers. That's why we've added extra sizing to standard sizes to extend use even after multiple washes. Strong Zipper: Concealed YKK zipper: High-quality concealed YKK zipper on the bedding. Practical branded zipper on the inside makes changing bedding easier and provides extra security while sleeping, unlike button closures. Easy Care: Machine wash and tumble dry. 60 degrees and suitable for tumble drying. Iron at low temperature. Bedding is tested for harmful substances according to Oeko-Tex Standard 100.
