The fabric is made of 200g nylon plain weave, making it lightweight, comfortable, and slightly stiff to the touch. The inner filling is 70g of new national standard 90% white duck down, with a double-layered lining to prevent down leakage. The inner lining is made of 600g of imitation mink fur, with a delicate feel, glossy color, and no shedding. It features a windproof stand-up collar design, a clean and crisp cut, inspired by USA police uniforms, with dropped shoulders and a fitted waist to accentuate an inverted triangle body proportion.
