The reason why  jackets have become the preferred outerwear for all outdoor enthusiasts is determined by their all-weather functionality. Stormwear is not mysterious, it is just a jacket. However, when this functional clothing was introduced to China from abroad, Chinese people started with its "free translation" to distinguish it from ordinary clothes, which is called "Stormwear".
The suit was originally used for the final charge in high-altitude snow capped mountains, where there is still 2-3 hours of travel from the peak. At this time, the down jacket is taken off, a large backpack is removed, and only a lighter piece of clothing is worn to move forward. This is the origin of the Chinese name
