A specially engineered durable Flex 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.

The Argonaut 3.0 is a new pattern of the award winning suit that has been developed for the unique BIOMAP fitting system which is available exclusively in store at Frog Dive. Imagine simply walking in and being scanned by sophisticated software years in the making to guarantee an outstanding fit for your own custom designed drysuit. No tape measures and no errors in sizing.

This allows a standard pattern suit size to be selected and tailored to the customers size and body shape, providing a custom fit without the full made to measure price tag. If a diver needs a fully custom pattern then the BIOMAP system provides all that's needed.
