Coolmax

Coolmax, a trademark of Invista, is a brand name for a series of moisture-wicking technical fabrics developed in 1986 by DuPont Textiles and Interiors (now Invista). The fabrics employ specially-engineered polyester fibres to improve "breathability" compared to natural fibres like cotton. 'Wick away' or 'wickaway' is a general term used for fabrics that are engineered to draw moisture away from the skin through capillary action and increased evaporation over a wider surface area.
