"The PROTEUS II is very flexible, but if in-between sizes, it's better to size up. The HYDROLOCK neck system works amazingly, but it is tight on your neck. I would compare it to a dry-suit neck."
Description

Proteus II Wetsuit 3mm – Unmatched Warmth & Performance✔

✔ Eco-friendly limestone neoprene | ✔ Hexcore & Thermoflex lining | ✔ Semi-dry seal system

The Proteus II 3mm is the warmest and most advanced dive wetsuit in its class. Designed to deliver superior thermal performance with minimal bulk, this suit sets the benchmark for 3mm wetsuits—outperforming many 5mm suits while offering greater flexibility and less buoyancy.

Crafted with greener limestone neoprene, Eco Carbon Black (made from recycled rubber tyres), and water-based Aqua-X glues, the Proteus II significantly reduces CO₂ emissions and eliminates harmful substances in its construction—making it a more eco-conscious choice for divers.

Featuring the renowned Hydrolock neck seal, Glideskin wrist seals, and internal PU ankle seals, this wetsuit is built to minimize water ingress and deliver a semi-dry diving experience. Double glued, blind-stitched, and taped seams further enhance insulation, while Hexcore lining across the torso ensures core warmth during prolonged dives. Thermoflex lining throughout the rest of the suit adds to the overall thermal efficiency.

Proteus Tauchanzug
Fourth Element

Fourth Element wetsuits

Combining super thermal Hexcore lining with an innovative double neck seal, the Proteus II is our highest performing dive wetsuit and the choice of many dive professionals around the world. Made from a more eco friendly limestone neoprene using recycled car tyres and water based glues, not compromising on performance.

Features

Proteus II - extra warm

Hydrolock neck system

A second, over-head closure to minimise water ingress.

Taped seams

As well as being glued and stitched, taping ensures seals are waterproof.

Glideskin wrist seals

Create a barrier at the wrist to prevent water entering.

Hexcore torso lining

Plush lining on the core for prolonged water exposure.
Recycled Rubber

One of the key ingredients of neoprene, Eco Carbon Black, is recycled by our wetsuit factory from post-consumer scrap tyres. This significantly reduces energy consumption and cuts CO2 emissions by 200g per wetsuit.
Limestone Neoprene

During the neoprene production process, limestone is used to replace petrochemicals to form rubber chips. You achieve the same performance as traditional neoprene, but with way less environmental impact.
Resources

After the neoprene creation process, the redundant trimmed materials will be recycled and reused in the mixing process to produce more neoprene sheets. Overall huge amounts of raw materials are saved, energy consumption is reduced and waste water and air emissions are minimised during production.
