Material Options

Lightweight Stealth Fabric Choice

The Fourth Element Argonaut 3.0 offers three fabric choices, with the Stealth variant being the lightest and most travel-friendly option.

This nylon trilaminate construction provides excellent freedom of movement while maintaining durability, making it perfect for divers who prioritize mobility and portability without compromising on performance.

Zipper System

Easy-to-Use YKK Aquaseal Zippers

The Argonaut 3.0 features a cross-chest entry system with high-quality YKK Aquaseal zippers running from right shoulder to left hip.

This unique placement not only avoids weakening the fabric around the purge valve but also makes it remarkably easy to open and close even while wearing thick gloves, enhancing convenience and reliability.

Fit Technology

Redesigned Telescopic Torso System

The innovative telescopic torso design incorporates a suspenders system with crotch strap that pulls the suit snugly into the body for an optimal fit.

This engineering ensures the suit moves naturally with your body, reducing bulk and improving streamlining while maintaining comfort throughout your dive.

Mobility Design

Exceptional Arm Range of Movement

The Argonaut 3.0’s design prioritizes unrestricted movement, particularly in the arms and shoulders.

The Stealth fabric’s flexibility combined with the suit’s articulated construction allows for natural, comfortable movement both above and below water, making it ideal for technical diving and extended underwater work.

Articulated Design

AFT Knee Articulation System

The Articulated For Trim (AFT) design features specially patterned knees that facilitate easier bending and a more natural horizontal diving posture.

This motorcycle suit-inspired construction reduces resistance when in trim position and proves especially beneficial when wearing thicker undergarments, enhancing overall diving comfort.

Ease of Use

Streamlined Donning Process

Getting into the Argonaut 3.0 is designed to be straightforward and efficient.

The custom fit achieved through Fourth Element’s BIOMAP system, combined with the suit’s thoughtful design features, ensures that donning the suit is a smooth process that gets you ready for your dive quickly and comfortably.

Boot Options

Premium Tech Boot System

The Argonaut 3.0 offers multiple boot options, including these 2.5 mm compressed neoprene Tech boots.

These boots provide excellent traction and comfort while being easy to slip into most fins. The thinner profile reduces bulk while maintaining warmth and protection, perfect for technical diving applications.

What other customers say:

This is my second purchase from DRIS and I couldn't be happier. I sent my drysuit in for inspection and repair and they were really easy to deal with, responsive, and did a great job.

I had an item back ordered and they were quick to let me know and give me the choice to wait for everything or send it in two packages. Great customer service and sense of humor! (They have the best "your order has shipped" emails)
