This men’s 5/3mm full length wetsuit is designed for cold to cool water conditions where warmth retention and water sealing are critical. The suit uses a 5mm neoprene core through the torso for thermal insulation, paired with 3mm neoprene in the arms and legs to maintain paddling flexibility and mobility.

Sealed internal seams reduce water ingress and improve durability in high-stress areas. A chest zip entry system limits flushing compared to back zip designs and allows a closer, more watertight fit around the upper body. The black and grey colourway offers a neutral, functional appearance suitable for year-round use.

Why choose this product

Frequently Asked Questions

What water temperatures is a 5/3mm wetsuit suitable for?
A 5/3mm wetsuit is typically used in cold to cool water conditions, generally around 10–16°C, depending on wind, air temperature, and personal cold tolerance.

How does a chest zip differ from a back zip wetsuit?
Chest zip wetsuits reduce water flushing by limiting the entry opening size. They also improve upper-body seal and flexibility compared to traditional back zip designs.

Are sealed seams the same as fully taped seams?
Sealed seams reduce water entry by sealing stitch holes internally. Fully taped seams add an additional layer of reinforcement, but sealed seams still provide effective water resistance and durability.

Is this wetsuit suitable for other water sports?
Yes. While designed for surfing, it can also be used for other cold-water activities such as paddleboarding.
