Windproof trousers used on the 1933 Everest expedition

Windproof trousers, made by Howard Flint Ltd., London, from equipment used on the 1933 Everest expedition by Sir Jack Longland

Mount Everest has some of the highest windspeeds in the world. The wind makes it feel particularly cold and especially when it passes through unsuitable clothing. Windproof outerwear was a priority for the expedition. In his book, expedition leader Hugh Ruttledge said: “One has yet to find the man brave enough to appear publicly in England in this dress, but of its utilitarian value, indeed of its necessity, there can be no question”. These trousers, made by Howard Flint, were worn with a matching jacket, which had a detachable balaclava that could be used for extra protection.
