Argonaut 3.0 Drysuit - Made to Measure

Price on application

The Argonaut 3.0 is built to your body, not picked off a rail. We measure you here at the shop using a Bio Mapping Plate, which captures your proportions properly rather than relying on a tape and a guess, and we photograph the session so Fourth Element are building to a verified record. The quote follows once those measurements and photographs are finalised - which is why there is no price on this page.

Contact us to book a fitting and we will come back with a firm quote and a lead time.

Three fabrics

Flex - the most mobile of the three. Moves with you through the shoulders and hips, which is what you want on a long deco hang or running a reel one-handed. The default choice for most divers.

Stealth - the heavy-duty shell, for wreck penetration, cave work and anywhere the suit takes a beating from steel and rock rather than sand. Tougher, and stiffer for it.

Stealth Hybrid - Stealth fabric on the seat, knees and shoulders where suits actually fail, lighter fabric everywhere else. Survives the abuse without the whole-body stiffness of a full heavy shell.

Colours

Black, Anthracite, Deep Blue or Teal. Body and legs are specified separately, so the suit can be plain or two-tone.

Seals - fixed at manufacture

Neck: neoprene, or the Si-Tech ring-mounted silicone system. The ring system lets you change a torn seal yourself - a five-minute job at the dive site instead of a fortnight at a repair shop.

Wrists: neoprene, or the Ellipse changeable silicone system.

Dryglove rings: PSI or Si-Tech QCP. A large-hands QCP version exists for divers whose hands will not pass through standard rings - take it only if you need it, because a larger opening is harder to seal.

P-valves

Si-Tech Trigon, Fourth Element's own Light Monkey unit, or Halcyon. All balanced, meaning ambient pressure sits on both sides of the valve so it drains at depth rather than only in the shallows - the difference between a valve that works on a two-hour deco dive and one that works in the shallows. The She Pee 3.0 is the female system.

What to order alongside

All stocked separately and listed on the site: Heavy Duty Dry Gloves, the Ellipse dryglove system and suit rings, glove rings, sealing and dryglove o-rings, retaining bands, wrist stiff rings, the o-ring pry tool, silicone grease and the hard case, plus PSI dryglove systems and retainer rings.

Undersuit matters as much as the suit: Arctic X is the warmest we carry, Halo AR the technical standard, with Arctic and the J2 base layer range beneath. Size the drysuit with the undersuit you actually intend to dive in, not the one you already own.
