Classification of outdoor clothing

Outdoor clothing can be mainly divided into three types: underwear, thermal layer and outerwear.

Underwear

The main purpose of outdoor underwear is to keep human skin dry. If the sweat from the human body causes the surface to evaporate, it will take away the huge heat of the body and make people feel cold. Therefore, underwear should be made of synthetic fiber material, avoid wearing pure cotton and wool underwear.

The role of warm clothing is to form an air layer in the clothing. Air is a good heat insulation medium. After an air layer is formed in the warm clothing, the outside cold air is separated from the body to achieve the purpose of maintaining body temperature.

Coat

Outerwear for mountaineering and outdoor sports generally refers to clothing such as jackets, jackets, and raincoats. Its main functions are waterproof, windproof and tear-proof. With the development of science and technology, waterproof and breathable fabrics such as GORE-TEX and FIRST-TEX have been developed for Jackets. The principle is that in the film state, the diameter of the small holes on the surface is just between the water molecules and the steam molecules. The steam molecules can pass through, but the water molecules are blocked, so as to achieve the effect of waterproof and breathable.
