Vintage rubber swim fins titled 'Otarie' by Aqua Lung US Divers

These Aqua Lung Otarie swim fins were manufactured by US Divers, a pioneering company in diving equipment founded by Jacques-Yves Cousteau and Émile Gagnan in the mid-20th century. The Otarie model represents the evolution of recreational diving gear during the 1960s-1970s when scuba diving became increasingly accessible to the general public. Full-foot rubber fins like these were standard equipment for both recreational divers and military applications during this era. Vintage diving equipment appeals strongly to collectors of maritime history, scuba diving enthusiasts, and those interested in mid-century sporting goods. These fins are valued for their historical significance in the development of underwater exploration technology and their connection to the legendary Cousteau legacy. Collectors appreciate original examples with clear maker's marks and intact rubber, as they represent an important chapter in the democratization of ocean exploration.
