O, A and S are the three initials of the founder's name (Oliver Adam Sebastian). The brand was born during his numerous trips to the family summer home in Barcelona. It all started with Oliver continuously supplying his friends with the rare product of espadrilles, which until 2010 couldn’t be found in all of Scandinavia. The espadrilles were soon joined by swimwear, and OAS grew into the resort brand it is today - established in countries worldwide to provide the brand's customers with year-round vacation wear.
