Product Information

Full details

The KONA 5/4mm Winter GBS Back Zip Wetsuit is designed for cold-water surfers and ocean enthusiasts who need reliable thermal protection in UK and European winter conditions. It provides exceptional warmth and flexibility through its specialized thermo-stretch lining and high-grade neoprene, though the back-zip entry requires more shoulder mobility to enter compared to front-zip alternatives.

FAQs

What temperature range is this suit for?

This suit is specifically designed for cold water temperatures between 8°C and 12°C.

How do I maintain the YKK zip?

Rinse it with fresh water after every use and avoid forcing the zip if it encounters resistance; clear any grit immediately.

Can I machine wash this wetsuit?

No, never machine wash or tumble dry your wetsuit as this will destroy the neoprene and seam integrity.

Why is the lining quick-dry?

The thermo-stretch quick-dry lining is designed to wick moisture away and dry faster, making your second session of the day more comfortable.

What is the benefit of GBS seams?

Glued and blind-stitched (GBS) seams prevent water from leaking through the stitching holes, keeping you much warmer than flatlock seams.

Troubleshooting

Water flushing into the back area

Check that the internal hydro-bloc barrier is pulled up high and lying flat against your back before zipping the suit.

Zip feels stiff or sticks

Rinse the zipper area thoroughly with fresh water and remove any sand particles; apply a silicone-based zipper lubricant if necessary.

Wetsuit feels tight in the shoulders

Ensure the suit is pulled up fully into the crotch area to allow proper distribution of the neoprene through the torso.

Pros and Cons

Pros

  • Excellent warmth for frigid winter swells
  • High-stretch neoprene for improved range of motion
  • Durable YKK back-zip hardware
  • Quick-dry lining reduces chill in damp suits
  • Reinforced knee pads for added protection

Cons

  • Back-zip entry can be harder to seal than chest-zip suits
  • Less flexible across the chest due to the zip construction
  • Requires careful rinsing to maintain zipper integrity

Setup, Compatibility & Care

To put the suit on, step into the legs first, pull the suit up to your waist, and then carefully work your arms in one at a time. Pull the back zip up steadily, ensuring the internal hydro-bloc barrier is flat against your skin. After every session, rinse the wetsuit thoroughly with fresh, cold water. Avoid drying the suit in direct sunlight, as UV rays break down the neoprene and accelerate degradation. When storing, use a wide-shouldered hanger to prevent shoulder stretching. Always ensure the zipper is free of sand or salt crystals to keep it sliding smoothly.
