Size: XXXL Hoodie Sweatshirt Wear Set Up Autumn/Winter/Spring Clothes Warm Fashion Casual Long Sleeve Top and Bottom Set Material Composition: 100% Polyester. With a simple, timeless design, this set can be used not only for sports but also for everyday wear and loungewear. Made of moisture-wicking and breathable polyester material, you can stay comfortable even when you sweat. The overall thickness is just right, and the fabric is soft to the touch, providing warmth when worn, but it won't feel stuffy in the cool seasons of spring and autumn. In winter, you can combine it with a jacket or outerwear for added warmth and fashion. The elastic waistband provides a comfortable fit, and the drawstring allows you to adjust it to your waistline. Both the top and bottom have pockets on the sides, convenient for carrying small items. This is a stylish set-up jersey, perfect for casual wear and loungewear, as well as for active scenes such as walking, running, and training. If you prefer a more relaxed fit, we recommend purchasing one size larger.
