Fourth Element PROTEUS II Wetsuit

Fourth Element

Regular price $439.00

ADVANCED WETSUIT TECHNOLOGY

The warmest 3mm dive wetsuit on the market and the highest performing 5mm wetsuit in its class according to independent testers. The Hydrolock neck seal minimises water ingress combined with the Hexcore thermal lining to maximise warmth.

The Proteus II is arguably 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.

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 5mm suit is a versatile performer. With improved fit, the suit is easier to don that the classic Proteus, but its thermal performance is even better. We recommend the 5mm suit for prolonged dives in temperatures of 19C and warmer. 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).
