Aqua Lung — Where Scuba Diving Began

In 1943, Jacques-Yves Cousteau and engineer Émile Gagnan developed the demand regulator that made scuba diving as we know it possible — the device that automatically delivered compressed air to a diver at ambient pressure, allowing unrestricted underwater breathing for the first time. They named it the Aqua-Lung. The rights to manufacture and distribute it were held by La Spirotechnique, a division of Air Liquide. In 1952, the U.S. Divers Company was founded to introduce that technology to the American market, and the industry Cousteau and Gagnan created began to reach the broader public.

Over the following decades, the company went through multiple ownership changes before being sold to Montagu Private Equity in 2016, at which point it rebranded as Aqua Lung America, headquartered in Carlsbad, California. The U.S. Divers trademark continues as the brand for Aqua Lung's snorkeling line — a legacy name that traces directly to those 1952 origins. What began with one invention now spans a full catalog of diving equipment: boots, gloves, regulators, BCDs, dive computers, fins, masks, drysuits, wetsuits, and accessories.

Dive Boots

Aqua Lung's boot lineup covers warm through cold-water diving, each built around specific engineering details:

• Echozip 3mm and 7mm — ERGO anatomical design (patented) for a precisely fitted foot shape; secure zip closure. The 7mm version uses Supratex neoprene and a strong YKK zipper for genuinely cold-water performance.
• Superlow 3mm — designed for warm water; minimal seams placed specifically away from the foot's widest areas to prevent chafing; treaded sole for traction.
• Superzip 7mm — Supratex neoprene; YKK zipper; built for cold-water durability.

Dive Gloves

The Admiral III 2mm is built for warm-water diving: moderate thermal protection, excellent grip, and comfortable fit designed for tropical conditions where full wetsuit gloves would be overkill.

Regulators

The Helix Compact Pro Octopus brings the same performance as the Helix Compact Pro primary second stage in a compact, travel-friendly profile — a well-matched backup for any Aqua Lung primary regulator system.

Key Aqua Lung Technologies

ERGO Anatomical Design (Echozip): Aqua Lung's patented boot foot shape, engineered to follow the natural anatomy of the foot rather than forcing it into a generic shape. Translates to a more comfortable fit across long diving days.

Supratex Neoprene: Used in Aqua Lung's heavier-duty cold-water boot models for improved durability and resilience compared to standard neoprene, maintaining insulation and structure across repeated use in cold environments.

Frequently Asked Questions — Aqua Lung

Did Cousteau actually invent scuba diving?

Jacques-Yves Cousteau co-invented the demand regulator — the device that made practical scuba diving possible — along with engineer Émile Gagnan in 1943. While people had been diving with compressed air systems before, the demand regulator was the breakthrough that allowed a diver to breathe naturally at depth without a surface-supplied air line or a manually controlled valve. Cousteau and Gagnan's Aqua-Lung was the direct ancestor of every scuba regulator in use today.

What is U.S. Divers and how does it relate to Aqua Lung?

U.S. Divers Company was the name under which Aqua Lung equipment was introduced to the American market in 1952. After multiple ownership changes and the 2016 rebrand to Aqua Lung America, the U.S. Divers trademark was retained as the brand name for the snorkeling product line.

What is the difference between the Echozip 3mm and Superlow 3mm boots?

Both are 3mm warm-water boots, but they address different priorities. The Echozip uses Aqua Lung's patented ERGO anatomical design for a precise anatomical fit, making it the better choice for divers who've struggled with standard-shaped boots. The Superlow is engineered to minimize seams at the foot's widest areas, making it the better choice for divers who've had chafing or pressure issues at those contact points.

What is Supratex neoprene?

Aqua Lung's heavier-duty neoprene compound used in the Superzip and Echozip 7mm cold-water boot models, providing improved durability, resilience, and cold-water thermal performance compared to standard neoprene formulations.
