From a low-fi start in the '80s when physician Oskar Metsavaht designed some cold-weather outfits for an expedition to climb South America's highest mountain – Aconcágua – with some friends, Osklen has grown to establish a reputation as an adventurous brand. Clothes of that kind simply didn’t exist in Brazil at the time, and were such a big hit that Metsavaht opened a snow-wear shop – ironically – in the middle of oven-hot Rio de Janeiro.

Today, Osklen brings together the concept of adventure clothing and cutting-edge design, with a sprinkling of eco-awareness (organic cottons and fish skin have both featured in past collections). The Rua Oscar Freire store is fitted out with rustic woods and iron, in a light, laid-back space. Peruse the fashion forward clothes, grouped in the store by theme, be it pattern, cut or fabric type.
