Fourth Element Proteus II 5mm wetsuit

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.

The Fourth Element Proteus II tops the market in terms of performance and warmth. It sets the bar quite high for their competitors in the 3mm and 5mm segments.

Their Hydrolock inner neck seal and glideskin wrist seals provide a perfect seal on your skin to stop water from rushing in.

The seams are all double glued, blind stitched, and taped to keep you warm and the cold water out.

There are additional Hexcore linings on the torso that increases thermal protection in case required on a longer dive.

This 5mm suit is not only easier to put on and take off than the previous Proteus, but it has increased its thermal performance at the same time.

Recommended water temperatures are above 19C (66F) but this suit is fully capable of handling colder dives if desired.
