Guy Cotten, born in 1936 in Finistère, started selling fishing clothing on the quay at Concarneau in 1964, then set up a workshop making nylon oilskins lighter than traditional coated-cotton ones. The present company, Établissements Guy Cotten, dates from 1969. The Rosbras jacket, designed in 1966, became the brand's reference, and a workshop later opened in Trégunc.
In 1974 Alain Le Quernec drew the little yellow man used as the logo, and the slogan "L'abri du marin" followed in 1981. In 1988 the firm bought Piel from Pirelli, a survival equipment specialist, and later developed the TPS survival suit, used notably during the 1996 Vendée Globe.
Nadine Bertholom, the founder's daughter, has run the company since 2003. The brand equips fishermen and recreational sailors and has backed many sailors, including Roland Jourdain, Marc Guillemot, François Gabart and Jean Le Cam.
