Jacket, mbth jacket, also known as outdoor jacket, transliterated as jacket, is one of the necessary equipment for outdoor sports. Jackets are the first choice for all outdoor lovers because of their all-weather functions.
Jacket or outdoor jacket is transliterated into jacket in English. Jacket is not mysterious, but when this kind of functional clothing was introduced to China from abroad, China people started with its "free translation" to distinguish it from ordinary clothing.
When climbing the snow-capped mountains at an altitude of 2-3 hours from the summit, use the jacket first for final charging. At this time, you will take off your down jacket, take off your big backpack, wear only a lighter dress and go into battle lightly. This is the origin of the Chinese name "jacket".

Clothing characteristics
The so-called professional waterproof means that whether you are sitting in a wet place or walking in a stormy environment, you can effectively block the invasion of rain, snow, frost and snow, so that water can not penetrate into clothes and make you feel wet and cold; Breathability means that when you do a lot of outdoor exercise, your body naturally sweats and your skin exhales a lot of water.
If it can't be excreted quickly, it will definitely lead to sweat trapped between the body and clothes, which will make people soaked. On rainy days, it will make people feel wetter and colder. Especially in cold conditions such as mountains and canyons, it is very dangerous for the body to get cold and lose temperature, so good air permeability of clothing is very important.
The so-called windproof means that 100% prevents the air cooling effect. In the changeable natural environment, when the cold wind penetrates our clothes, it will blow away a layer of warm air near our skin. This layer of warm air is about one centimeter thick, with a temperature of 34-35 degrees and a humidity of 40%-60%.
Even a slight change in this warm air will make us feel cold and uncomfortable. When cold air blows into clothes, it destroys this warm air, leading to rapid heat loss and body temperature drop, and we will immediately feel a little chilly. This is the so-called air cooling effect.
