What is a jacket?

Jackets, also known as Outdoor Jackets, transliterated as jackets, are one of the essential equipment for outdoor sports.
The reason why stormtroopers have become the preferred outerwear for all outdoor enthusiasts is determined by their all-weather functionality. The charge jacket is not mysterious, it is just a jacket. However, when this functional clothing was introduced to China from abroad, Chinese people began to distinguish it from ordinary clothes by interpreting it as "charge jacket".
The sprint suit was first used for the final charge when climbing high altitude snowcapped mountains, with a distance of 2-3 hours from the peak. At this time, the down jacket is removed, the backpack is unloaded, and only a lighter piece of clothing is worn to advance lightly. This is the origin of the Chinese name "sprint suit".
