Selection principle of outdoor clothing

1. Convective heat dissipation: When the cold wind penetrates the inner layer of the clothes and takes away the warm air from the skin surface, the heat is dissipated; therefore, the outer layer of clothes must be windproof.

2. Conductive heat dissipation: heat dissipation caused by direct contact with cold objects, especially when the inner layer of clothing is wet; therefore, the outer layer of clothing must be able to prevent rainwater from penetrating, and have high air permeability to prevent moisture from accumulating Inside the clothes, the inner layer of clothes can actively transmit the moisture caused by sweat to the outer layer for discharge.
