Rab is a United Kingdom mountaineering clothing and camping equipment manufacturer and supplier. The company was founded in Sheffield, South Yorkshire, by mountaineer Rab Carrington (born 1947 in Glasgow, Scotland). After studying at the University of Glasgow he became a full-time mountaineer and a climbing partner of the distinguished mountaineer Alan Rouse. He learnt how to make sleeping bags during an aborted expedition in Argentina in 1973 and started his own business in 1981, sewing the first sleeping bags himself in his attic.
