Abstract: A method of reducing cost of waterproof breathable clothes and improving breathing quality of waterproof non-breathable clothes uses more than two kinds of waterproof cloths with different water vapor permeability according to the physical characteristics of moisture, along with the structures of clothes themselves. The waterproof cloth with higher water vapor permeability is applied to parts of clothes most requiring heat dissipating and breathing (the place where moisture accumulates or generates), and the waterproof cloth with lower water vapor permeability or the waterproof non-breathable cloth is applied to parts of clothes less or not requiring heat dissipating and breathing. In other words, the proper moisture-permeable cloth is applied to each part of the clothes with respect to the requirement of heat dissipating and breathing.
