The Proteus II is one of the best performing wetsuits available on the market for warmth and comfort. 

Water ingress is minimised using Fourth Element's well know Hydrolock neck seal and Glideskin wrist seals which keep you warmer for longer. Thermal protection is enhanced by the seams being double glued, blind stitched and taped, massively reducing flow of water throughout the suit. This range also has Hexcore linings incorporated into the suit for extra warmth around the core of the body. 

This 3mm wetsuit is so advanced its warmth is often compared to 5mm wetsuits, only with greater flexibility and less buoyancy. This suit is designed to snugly fit a female shape with choices in length for greater fit. 

Recommended by Fourth Element for water temperatures 23C and warmer, though it is used by many divers in cooler waters.
