The fourth element Proteus II is arguably the highest performing wetsuit on the market and is often the benchmark to which other suits are compared in terms of warmth.
By combining the Hydrolock inner neck seal and Glideskin wrist seals, water ingress is minimized. 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 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.
