I remember using the oilskin ones - and the smell - which was the same as the table cloths used in school at lunchtime. I never wore a souwester IIRC, but my dad did. Oilskin capes were very effective but hefty pieces of kit and we were very happy when modern plastic ones started to be available in the early 1960s. Used to wrap the cape around the spare tub, and carry it strapped under the saddle with a spare toestrap. In recent years only one of the people I ride with has used a cape, and the disadvantages have been very obvious - any headwind resulting in her speed dropping dramatically
