“At the heart of the pattern development was the quest for improved mobility, stronger construction, greater streamlining, easier gas management, lighter weight and easier donning and doffing – but most importantly, the introduction of an improved women’s pattern, that fits beautifully.” – Fourth Element



Lightweight, hardwearing protection

Made with Nylon Trilaminate fabric to provide the ideal combination of stretch and lightweight durability, donning the Argonaut Stealth feels more like putting on your favourite jacket. The unparalleled freedom of movement thanks to a combination of the fabric’s performance with Fourth Element’s unique pattern, makes this a most versatile drysuit.


Durability and comfort

A specially engineered durable Flex Polyester Trilaminate material is used throughout, making the Argonaut Flex an extremely rugged suit. This fabric has already been specified for military use and features hardwearing fabrics laminated with a flexible butyl layer for the ideal balance of durability and comfort.


Durability and freedom of movement

Using a combination of the Stealth fabric on the torso and arms of the suit, with Flex trilaminate lower body, the Hybrid suit gives excellent mobility, outstanding durability and the ultimate fit, thanks to the unique BIOMAP® system and Argonaut 2.0 design.
