"The Aleut American Indians ( who lived in the Aleutian Islands between Alaska and Russian Siberia) needed a totally waterproof jacket for hunting in their double cockpit kayaks called Baidarkas. They used dried seal or whale intestines and sealed the seams with animal glues to make a ‘kamleika’ as illustrated.

To check effectiveness after sealing, the Aleuts would tie off the cuffs and neck and fill with water. Proof indeed that seam sealing is ancient and not modern. The picture below dates from 1910, but it is not known how long these practises continued.

One of the great all time mountain product innovators, Allain developed a system which combined a short down sleeping bag for bivouacs with a long waterproof over-garment, for which he used the French word for ‘cowling’ ie ‘cagoule’, a long rubberised silk garment as part of his bivouac gear in the 1930s. - See more at: http://innovation-for-extremes.net/gear-timezone/product-biography/product-biography-the-waterproof-jacketpart-1-1820-1938/#sthash.ryUWPmQF.dpuf"
