Breathable Fabrics and Comfort in Clothing

Breathable fabrics facilitate the loss of water vapor from clothing and reduce condensation. Three varieties, proofed cotton, microporous, and hydrophilic polypropylene, are measured for water vapor permeability, hydrostatic head, abrasion, and bending length. In general, breathability is insufficient to prevent condensation without due regard to functional garment design. -- AATA
