Fourth Element Women's Proteus II Wetsuit
The Warmest dive wetsuit on the market
The Proteus II is the highest performing dive wetsuit on the market. Available in 3mm and 5mm, the Proteus II is often the benchmark to which other dive wetsuits are compared in terms of warmth. Our wetsuits are made using a greener and more eco-friendly limestone neoprene with Eco Carbon Black which uses scrap rubber tyres cutting C02 emissions by 200g per wetsuit. We also use water-base Aqua-X glues in lamination and construction of our neoprene suits meaning we’ve eliminated the use of harmful substances.
By combining the now famous Hydrolock inner neck seal and Glideskin wrist seals, water ingress is minimised. Seams are double glued, blind stitched and taped to provide outstanding thermal protection throughout the dive. Additional Hexcore linings on the body core provide enhanced thermal performance where it is most needed for prolonged water exposure.

The Proteus II is one of the most advanced wetsuits available, offering exceptional thermal performance, comfort, and flexibility.
The 3mm Proteus II is probably the only 3mm wetsuit in the world to feature such advanced technology, allowing it to perform more like many standard 5mm suits. With greater flexibility, reduced buoyancy, and impressive warmth, it’s ideal for water temperatures of 23°C (73°F) and warmer – though many divers confidently take it into cooler waters.
The 5mm Proteus II is a true all-rounder. Easier to don than the classic Proteus, it offers an improved fit with even better thermal performance, making it perfect for prolonged dives in waters of 19°C (66°F) and warmer.
For colder conditions, both the 3mm and 5mm suits can be enhanced by layering with a Thermocline vest and shorts underneath, along with a 3mm or 5mm hood.
