Opis

Waterproof breathable fabrics are designed for use in garments that provide protection from the weather that is from wind, rain and loss of body heat. Clothing that provides protection from the weather has been used for thousands of years.The term 'breathable' implies that the fabric is actively ventilated. Breathable fabrics passively allow water vapour to diffuse through them yet still prevent the penetration of liquid water.Military waterproof protective clothing known as 'foul weather clothing' - is produced to the highest standards of performance. Breathablility is meaningless without a high standard of waterproofness and initial hydrostatic head of 500 cm of water (50 kPa) for high quality products to 130 cm of water (13 kPa) for lower grade products.Garments which are both waterproof and breathable help to provide the wearer with a greater level of comfort in many adverse situations. Comfort has become an important consideration for the consumer when purchasing performance apparel. Waterproof garments, which are also breathable can command a significant price premium. However, such items are generally more affordable today than they were in the past.
