ABSTRACT OF THE DISCLOSURE The invention disclosed is a novel composite material useful in tent construction, particularly for cold-weather use. The novel composite includes an outer water-vapour permeable, substantially wind-proof layer, a thermal insulating layer adjacent the outer layer, a water-vapour barrier layer adhesively bonded to the thermal insulating layer and an inner water-absorbent layer which is preferably flame-resistant. Condensation problems which occur in tents used in cold-weather conditions are minimized by the provision of an inner water-absorbent layer which absorbs and directs condensed water-vapour to the tent floor.
