Aqua Lung breathes life into water trekking. It makes scuba diving and snorkeling gear and related accessories for recreational, technical, and military customers. The company’s name was established more than 60 years ago when Jacques-Yves Cousteau and Emille Gagnan created the first aqua-lung. Aqua Lung sells its products — such as regulators, masks, fins, snorkels, and wetsuits — through selected dive shops and the firm’s catalog. Brands sold and distributed by the company include Aqua Flex, Aqua Lung, Apeks, Impulse, SeaQuest, and Tyke. Part of the Air Liquide business, the company and its sister company Aqua Lung International sell its products in more than 30 countries.
