I’ve attracted some mockery for this one, but I believe a true design classic is the hardwearing yellow oilskin. I’ve seen so many lightweight nylon/goretex waterproofs expire after a couple of years, I deided to go back to basics;
It is about as featureless as a jacket can be, but does the basic stuff well- keeping the rain out. Its only downside is its extreme weight, and the ‘Norwegian Fisherman’ comments some of my snootier friends and family make. This particular jacket actually saved my elbow from a scrape during my recent bike slip- a lesser waterproof, I am sure, would have ripped quite badly!
