(Measuring Guide)
Drygloves offer little in terms of thermal protection, so why not add a pair of dryglove liners to keep your hands warm during your dive.
Please select your choice of neck seal. Latex and neoprene are offered, alongside the Si-Tech Quick Neck system which allows a quick and easy change of silicone neck seal. Please note: currently the new 3.0 neoprene warmneck collar is only available with neoprene and latex neck seals.
We are pleased to offer Apollo valves, as well as Si-Tech and Apeks valves. To find out more about each valve type, click the question marks on each option.

Our Standard and Tech Dryboots come with ergonomic insoles to help augment the fit and comfort of your boots. All our boot/sock options allow room for a Xerotherm sock underneath. IMPORTANT – if you are between sizes, or plan on wearing thicker socks, we recommend sizing up.
Each Argonaut comes with a neoprene diving hood, free of charge. Please select your hood type and size. If between sizes, we recommend sizing up.
Based on Head Circumference
Two generous pockets are included as standard with each Argonaut drysuit. Each pockets contains two bungee loops inside the main pocket along with a wetnotes sleeve and a D-ring. The outer zipped mini pocket contains two further bungee loops. Customers can opt to have just one or no pockets. At 3.5l volume per pocket, Argonaut pockets are one of the biggest pockets offered on the market.
Opting for a p-valve offers comfortable relief when on longer dives. The p-valve can be mounted to either leg.
Customers have the choice of fitting their p-valve on the left or right leg as worn.
(As Worn)

Allowing exceptional mobility and durability, the rip-stop nylon outer layers protect a butyl-rubber core in this trilaminate material to create a highly flexible, yet strong fabric. Select this option for maximum mobility, and minimum bulk and weight.
The two fabrics can be combined to form our ‘Stealth Hybrid’ suit with the lightweight mobility of the Stealth fabric on the torso and arms, combined with the ultimate durability of the Flex fabric on the legs.
Lightweight and breathable, the Kevlar drysuit is particularly suited to divers spending any amount of time out of the water between dives. The Kevlar fabric allows water vapour to pass through the suit, helping to reduce condensation forming on the inside of the drysuit.
A hard-wearing, tried and tested fabric with a butyl-rubber core and polyester faces that retains some stretch. This is the choice of fabric of military and professional divers all over the world. Select this option for a super-durable suit.
The best of both worlds, durable Flex bottom half with a breathable Kevlar upper half.
Hard-wearing and inexpensive, latex seals are a popular choice for recreational and technical divers alike.
Our 3mm neoprene wrist seals are considered by some divers to be more comfortable than latex seals and stand up to abrasion well.
The Ellipse wrist system uses silicone seals and provides an easy solution for dry gloves. Designed by fourth element and manufactured by Si-Tech, the seals can be easily swapped out enabling quick repairs. If you wish to wear drygloves, please select the ‘Ellipse Dryglove Attachment’ option.
Popular with technical divers, Si-Tech silicone wrist seals offer the ability to quickly and easily change the seals. The QCS Oval system fits most hand sizes, but for hands measuring 25cm or more, please consider latex or neoprene seals instead.
Machined from anodised aluminium to protect against corrosion, this premium dry glove system is designed to work with the Si-Tech PU suit ring to allow a quick and easy change of silicone wrist seals. The glove-to-suit sealing o-ring seals confidently with little effort thanks to a user-friendly colour-coded bayonet lock.
The Si-Tech QCP XL (Quick Cuff Platform) is only recommend for divers with large hands, who may struggle to get their hands through the oval ring of the Ellipse system. Using larger, round rings, the Si-Tech QCP XL system also has the benefit of easily replaceable silicone seals.
The Si-Tech QCP XL Round system is very similar to the QCP Oval system but is circular in shape which allows a more comfortable fit for those with bigger hands.
Should you want to wear drygloves with your Si-Tech QCS Oval wrist system, please select this option. The Antares kit will allow you to fit a dryglove on to your QCS Oval ring system.
Should you want to wear drygloves with your Si-Tech QCP XL Round wrist system, please select this option. The kit will allow you to fit a dryglove on to your QCP XL Round ring system.
The lightweight dryglove offers excellent dexterity with textured palms and fingertips. Inexpensive yet durable, they can be paired with fourth element's glove liners for extra warmth.
These thicker drygloves are well-suited for cold or technical dives, including wreck dives. The whole of the glove has a robust texture offering excellent grip and durability. The heavyweight dyglove can be worn with fourth element's glove liners underneath for added thermal protection.
Xerotherm gloves are a low-profile liner option with exceptional warmth. Made using Polartec® Powerstretch® originally developed for NASA, the Xerotherm gloves give excellent dexterity.
Halo A°R gloves are made with the same A°rgon aerogel as our Halo A°R undersuit. With superior warmth to weight ratio, these gloves are the warmest option - perfect for cold water diving.
G1 Glove Liners are constructed from low profile 1.5mm hydrofoam. This, combined with the bamboo-derived lining, gives a warm glove with the added confidence that in case of dryglove failure they will retain a degree of thermal protection.
Latex neck seals are hard-wearing and inexpensive, these are a popular choice for recreational and technical divers alike.
Our 3mm neoprene neck seals are considered by some divers to be more comfortable than latex seals and stand up to abrasion well.
The Si-Tech option utilises the Quick Neck System. The more flexible ring offers greater comfort and ease of movement with the added benefit of being able to change out the silicone neck seal quickly and easily. A Si-Tech combi-tool is included.
The Standard Dry-boot is the more rigid and heavyweight of the two dry-boot options. It is well suited for shore-entry dives or for when terrain is rough.
The Tech Dry-boot has less vulcanised rubber, making it lighter-weight and more flexible and is particularly popular with divers likely to be performing more complex finning.
Alternatively, you can opt for our 2.5mm compressed neoprene socks which allows you to wear your own choice of boot on top. Please check the sock size chart carefully. The compressed neoprene socks will allow a thin thermal sock underneath (such as a Xerotherm sock). If you are between sizes, or plan on wearing thicker thermal socks, we recommend sizing up.
Each Argonaut drysuit is supplied with a fourth element neoprene hood of your choice. Please choose from 3mm, 5mm, 7mm and 7mm Coldwater (with skirt).
Two generous pockets are included as standard with each Argonaut drysuit. Each pockets contains two bungee loops inside the main pocket along with a wetnotes sleeve and a D-ring. The outer zipped mini pocket contains two further bungee loops. Customers can opt to have just one or no pockets. At 3.5l volume per pocket, Argonaut pockets are one of the most generous available.
The Si-Tech is a balanced, pressure compensated p-valve. Its design is simple and easy to clean. It is very low profile at less than 2cm high when mounted to the drysuit.
Machined from solid Delrin®, the Light Monkey p-valve is a robust, balanced p-valve with engraved fourth element logo. It comes with a ‘quick disconnect’ to aid quick and easy changes.
With a solid Delrin® body, the Halcyon Streamline p-valve is a robust, balanced p-valve allowing easy operation, even when wearing drygloves.
The Si-Tech valves come with the ‘Balder’ push-to-fit rubber hose, designed to be used for low dexterity (such as wearing thick drygloves). Boasting excellent responsiveness to small changes in pressure, the ‘Shell’ inflate valve and ‘Argo’ dump valve offer precise control and low profile. Made in Sweden.
The Apeks low profile ‘Swivel’ inflate valve and automatic dump valve, with fast rates of inflation and rapid exhaust flow, are a robust and reliable choice. The Apeks valves come with an Apeks rubber hose and Seatec inflation nipple on the inflate valve. Made in the UK.
Apollo Bio-Valves. These valves, designed and manufactured by Apollo in Japan and are low profile, intuitive to operate and simple to maintain, even in the field. Activated with highly responsive side mounted levers in both cases, the inflate valve needs a gentle squeeze rather than push onto the chest. To manually operate the exhaust valve, the wearer can simply slide a hand up the arm to touch the edge of the valve. The Apollo valves come with a Hydpro PU-coated braided hose.
Glove / hand size: Wrap a tape measure around the palm of the hand just below the knuckles, make a fist and take the measurement.
BIOMAP photos may take up to two working days to evaluate. Please feel free to send any test photos to argonaut@fourthelement.com for feedback, or to ask any questions you may have. Before uploading photos please read the Biomap Photo Guide (opens in a new window) or watch the video tutorial for details of the photo specifications required. Failure to follow these guidelines can delay the drysuit production by approximately 2 weeks.
You can also specify a DIR/GUE exhaust valve placement for any valve choice. The exhaust valve is placed further back on the arm to allow easier dumping of air when in horizontal trim with arms forward. This option is not recommended for divers with limited arm or shoulder mobility.
The shape and size of this ring system can be very pronounced on smaller suits, and some customers have found the system uncomfortable on their shoulders. Therefore, for petite customers, we would recommend an alternative neck seal option.
It is important to measure the customer accurately, in cm, using a tape measure. Please do not just take the customer’s word for it. Any height discrepancies picked up by the BIOMAP software will require a new height check, and will cause a delay in getting your suit in to production.
