The Fourth Element Proteus II Mens 3mm Wetsuit is the new and improved version of the popular Proteus Wetsuit range with warmer Hexacore lining and the range of seals around the suit keep you much warmer than other 3mm suits.



A new Hexacore plush lining over your core section traps water and keeps you much warmer during the dive. The honeycomb pattern increases the drying speed so the Proteus II is much nicer to put on before the second dive of the day. The rest of the suit has Thermoflex lining that is flexible and soft so you can move in your suit and stay warm.

Water ingress is minimised thanks to a vast array of seals all over the suit to slow the water from rushing in. Around your neck you'll find Fourth Element's Hydrolock inner neck seal that stops water from flushing through the zip and around your neck. Each wrist has Glideskin cuffs to stop the water flushing up your arms and the seams are now double-glued, blindstitched and taped to stop water from getting in.


  • Hexacore Thermal Lining on Torso
  • Thermoflex Thermal Lining
  • Blindstitched, Double-Glued & Taped
  • Internal Ankle Seals
  • Glideskin Wrist Seals
  • Hydrolock Neck Seal
  • Ultra Stretch Knee Pads


We recommend water temperatures of 23°C (73F) and warmer

Fourth Element Proteus II Mens 3mm Wetsuit - Features

FeatureProduct Specification
Ankle Seal
As with the neck and wrists, the ankle seals help to stop water be flushed into the suit through movement, trapping warm water against the skin and maintaining body temperatureClose
Entry Zip
The location of the entry zip. The zip is normally located in the centre of the front or rear of the suit but an offset zip can provide better comfort and aid donning and doffing. A wetsuit system usually has a rear entry zip on the full length piece and a front entry zip on the shorty. This is to avoid overlapping the zips which would create an uncomfortable ridge.Close
Rear Centre
Male or Female Fit
Wet suits are specifically cut for either men or women to provide a more comfortable fit.Close
Neck Seal
The neck seal is an important component of a wetsuit, providing a critical seal against cold water flushing into the suit. An entry level suit will feature a simple zip up collar whilst a high specification suit will have an adjustable closure and smooth finish to create a good seal.Close
The type of neoprene is important to you and the environment with cheaper petroleum based neoprenes and hypoallergenic limestone based neoprenes that are better for the environment.Close
The stitching can affect both the comfort and also the thermal protection that the suit can provide. Overlock is the basic stitching type, two pieces are stitched together creating a small ridge which can cause indentations in the skin and irritation. Flatlock and Blind stitch joins two pieces edge to edge providing a more comfortable flat finish. Blind stitch is different stitch pattern to flatlock that uses glue. The reduced number of needle hole and use of glue helps reduce water entry through the stitching. Seam sealed utilises a blind stitch join for comfort with the addition of an internal tape or liquid seal to create a better water barrier and prevent water seeping through the stitching.Close
Thermal Class
Class A: 7 - 12 degrees celcius Class B: 10 - 18 degrees celcius Class C: 16 - 24 degrees celcius Class D: 22 - 30 degrees celcius This is the thermal class given to the wetsuit by an independent testing body. Each class band covers a temperatures range that a suit certified for. This grading system currently only applies to full length suits, shorties are excluded. As an example two different 5mm thick wetsuits may look the same but one is more expensive and receives a higher grade. Without the grade to identify that the suit provides better thermal protection it is difficult to justify the higher price.Close
Class D
Thickness (mm)
The neoprene thickness of the wet suit. Generally speaking the thicker the neoprene the warmer the suit but there are other factors to bear in mind.Close
Wrist Seal
The wrist seal is another important barrier to prevent water flowing freely in and out of the suit.Close
