The Fourth Element Argonaut 3.0 Flex Drysuit is a testament to enhanced design, offering greater flexibility and more customizability for a personal drysuit experience. Engineered to move harmoniously with you, this new design ensures a perfect fit and freedom of movement while diving in trim, courtesy of its innovative AFT (Articulated For Trim). The Fourth Element Argonaut 3.0 Flex fabric (Flex Polyester Trilaminate) is specially engineered for durability and comfort to create a rugged suit. Originally designed for military use, the fabric is laminated with a flexible butyl layer to provide protection without becoming rigid.

Optimized for horizontal trim diving, the unique leg design of the Argonaut 3.0 promises unparalleled comfort in the water. It allows unrestricted freedom of movement across the knees and thighs, ensuring complete comfort throughout your dive. The redesigned telescopic torso fits closer to the body, resulting in a more streamlined silhouette, while the new warm neck collar permits swift and secure tucking away of hood skirts.

The drysuit features a composite dry zipper that runs from the right shoulder to the left hip, improving flexibility and fit while enhancing gas management when dumping air from the left shoulder. The Argonaut 3.0 can be specified with glued-in latex or neoprene wrist seals, the Ellipse wrist system, Si-Tech, QCP Ultima, or the new intuitive PSI system.

Fourth Element  Argonaut 3.0 Flex Drysuit

Designed for the award-winning BIOMAP measuring system by Fourth Element, the Argonaut 3.0 Flex Drysuit is a truly bespoke drysuit, crafted for adventure. The suit is the culmination of four years’ research and development and has been tested by expedition divers in some of the harshest environments on earth. You can find out more about the process on our Biomap page.

Whether you're exploring deep wrecks, diving in cold water or simply looking for a more comfortable drysuit experience, the Argonaut 3.0 Flex is an ideal choice. Its enhanced design and customizable features make it the perfect drysuit for any diving adventure.
