66North has been keeping Icelanders warm since 1926, when it started out making oilskins for fishermen and sailors battling the North Atlantic. Today its flagship stores sell beautifully made, weatherproof jackets, fleeces and knitwear built for the elements, with prices to match the quality. Even if you are only browsing, the shops are a lesson in Icelandic design. Look out for end-of-season sales for the best value, and consider a lightweight shell jacket, which proves genuinely useful in the countrys fickle weather.
