Filled with 100g of 3m Xinxueli professional-grade velvet cotton, featuring a unique meltblown technology.The fabric is made of imported Turkish denim. After being washed with water to fix the color, it retains the original texture of the cow while being more comfortable. The slightly cinched waist shape and the lambskin patchwork design prevent the fabric from looking bulky in winter, making commuting and going out stress-free.
