Size Guide
"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."

The 3mm suit is probably the only 3mm in the world to feature such advanced features, allowing it to perform more like other 5mm suits with greater flexibility, and less buoyancy. We recommend water temperatures of 23C (73F) and warmer, but we know of many divers who take it into much cooler waters. To get more out of any wetsuit in colder waters, combine it with a Thermocline vest and shorts underneath and use a hood (3mm or 5mm).

The Proteus II is the highest performing wetsuit on the market. Available in 3mm and 5mm, the Proteus II is often the benchmark to which other suits are compared in terms of warmth.

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.

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.


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.
