The Fourth Element Proteus II is a worthy successor to the original Proteus suit. Available in 3 mm thickness for Men, the Proteus II is set to redefine the warmest suit in its class.

Water ingress is minimised by a number of design features. Glide-Skin wrist seals and the now famous hydro-lock inner neck seal combine with watertight seams which are double glued, blind stitched and taped to keep the water out. Thermoflex linings throughout the suit provide excellent comfort and thermal protection. Additional Hex-Core 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 3 mm in the world to feature such advanced features, allowing it to perform more like other 5 mm suits with greater flexibility, and less buoyancy. Fourth Element recommends water temperatures of 23°C (73°F) and warmer, but they 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).

Suit has a back zipper entry with zipper tab leash for easy self-donning and doffing. The Proteus II is available in multiple sizes.
