[1] In the late 19th century Lewis Haslam, a Lancashire mill owner and politician, began to link the partnering of holes and warmth and with two medical colleagues, began experimenting with aeration; trapping air within the warp and weft of fabric.

The result was a fabric that provided a barrier between the warmth of the skin and the chill of the atmosphere and in 1888 they formed the Aertex Company.

During World War II the British Women's Land Army wore Aertex as part of their uniform and all the British and Commonwealth land forces in the Far East and Middle East wore Aertex bush shirts and jackets.
