Camel hair pants have the advantages of moisture-proof, warm, good elasticity, close-fitting, breathable and not easy to deform, and can provide good warm-keeping effect at the extreme temperature of -40℃. Wool pants are autumn and winter pants made of medium wool. They feel soft, smooth, warm and comfortable to wear. They are very light. Once they are in an environment of a few degrees below zero, they can meet the needs of keeping warm. If it is colder, it will not be enough.
