1. Classic diamond trademark: This is one of the symbolic elements of Mengkou, which is composed of two intersecting triangles and presents a diamond shape. The trademark design began in 1968 to represent the lightness, warmth and windproof characteristics of Mengkou down jacket. This trademark usually appears on the inside of the neckline, cuffs and some accessories of Mongolian down jackets, such as scarves, hats and gloves.
2. Square trademark: Compared with the classic diamond trademark, the square trademark is a relatively new design, which is more concise, fashionable and modern. The trademark usually appears on the front chest or back of Mengkou down jacket, as well as on some special edition products, such as limited edition down jacket and accessories series.
