ProteusII - Improved fit and thermal performance

The PROTEUS II is a worthy successor to the original Proteus suit. Available in 3mm and 5mm thicknesses, the Proteus II is set to redefine the warmest suit in its class.

Water ingress is minimised by a number of design features. Glideskin wrist seals and the now famous hydrolock inner neck seal combine with watertight seams which are double glued, blindstitched and taped to keep the water out.

Thermoflex linings throughout the suit provide excellent comfort and thermal protection.

Additional Hexcore linings on the body core provide enhanced thermal performance where it is most needed for prolonged water exposure.

Available in 3mm and 5mm versions.

5mm Wetsuits

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.

Tip: 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).

3mm Wetsuits

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.

Tip: 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).
