Fourth Element's Proteus II is one of the highest performing wetsuits available on the market. It's improved ladies fit and design mean that it's easier to don and doff whilst being incredibly comfortable to wear, with the addition of improved thermal protection.
Seals that are double glued, blind stitched and taped help to reduce water ingress in this unique design for prolonged warmth. Supported by the Hydrolock inner neck seal, Glideskin wrist seals and Hexcore linings it is a much warmer suit than most other 5mm's. The Hexcore lining is over the core of the body for core warmth during prolonged periods in the water.
Fourth Element recommend this suit for prolonged dives in water 19C and warmer.
