1. Look: See if there is any trademark, factory name and address, certificate of approval, quality grade, cashmere content, etc.

2, pat: pat a few times by hand, if there is no dust overflow, it is a reliable product.

3. Touch: Touch carefully to see how it feels. If the hand feels soft, the hair stalk can hardly be touched, which means that the cashmere content is high and the quality is good.

4. Pinch: The higher the cashmere content, the greater the shrinkage and the better the quality. A good down jacket can be reduced to the size of a pillow.

5, try on: be sure to try on clothes. Try it on and see how warm the down jacket is. A good down jacket can feel hot as long as you wear it for about 2 minutes.

6. Smell: A good down jacket should not smell bad. If there is obvious odor, it means that the down has not been strictly treated and washed and disinfected, and the quality is not good.
