My four-piece suit is all cotton, mainly due to the material. After all, sleep should be comfortable and the quality of sleep should be good. For example, the cotton four-piece suit in the cotton era is made of Xinjiang high-quality long-staple cotton, which is delicate and soft, with crisp fabric and easy to take care of. You can also rest assured that you can sleep naked, absorb sweat and breathe in summer and keep warm in winter.
