Features of jackets

The so-called professional waterproofing refers to whether you are sitting in a damp place or walking in a windy and rainy environment, it can effectively block the invasion of rain and frost, preventing water from penetrating into your clothes and making you feel damp and cold; The so-called breathability refers to the natural sweating of the body and the exhalation of a large amount of moisture from the skin when you engage in heavy outdoor activities. If it cannot be quickly expelled from the body, it will inevitably lead to sweat trapped between the body and clothes, making the whole body wet. In rainy weather, it will make you feel even more humid and cold. Especially in harsh conditions such as high mountains and canyons, the cold and loss of temperature of the body are very dangerous, so good breathability of clothing is very important.
The so-called wind prevention refers to 100% prevention of wind cooling effects. In the ever-changing natural environment, when 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 temperatures ranging from 34 ℃ to 35 ℃ and humidity ranging from 40% to 60%. Even slight changes in this layer of warm air can make us feel cold and uncomfortable. When cold wind blows into clothes, it destroys this layer of warm air, causing rapid loss of heat and a decrease in body temperature, we immediately feel a slight chill, which is the so-called air cooling effect.
