Gannex is a waterproof fabric composed of an outer layer of nylon and an inner layer of wool with air between them and was invented in 1951 by Joseph Kagan, a British industrialist and the founder of Kagan Textiles, of Elland, which made raincoats. Gannex raincoats were worn by Prime Minister Harold Wilson.
