Even at rest, humans lose about 30 g of water an hour through their skin. Physical activity and sport can increase this to 1000 g an hour. We often wear garments to protect ourselves against wind, rain, heat and cold. The denser the fabric, the better it protects us against the elements. However, such fabrics tend to be uncomfortable because the water vapor released by the skin as perspiration cannot escape quickly enough. Mountaineers, walkers and skiers know all about this problem. Coats and jackets made of PVC imitation leather provide excellent protection against wind and rain but are virtually synonymous with extremely poor wear comfort.
