Main purpose of this suit is to protect soldier against rain, wind and cold.It is worn over overall.Functionality and comfort of this suit are achieved by its specific characteristics. The fabric consists of three layers: -Inner layer which is close to the body does not absorb sweat but passes it through (in form of water -physiological vapor)towards the outer layer,leaving the skin dry. -Outer layer is water-repellent and protects against wind -Middle layer-membrane is made of pores that are 700 times larger than a molecule of water vapor and about 20000 smaller than water drop.This way the passing of water is prevented while passing of water vapor enabled. These characteristics provide permanent waterrepelance. The seams are laminated. Learn More
