Key Features to Look For

When choosing a cold water wetsuit, these features make a huge difference:

  • Thermal linings – Traps heat and dries faster
  • Glued & blind-stitched seams – Minimises water entry
  • Sealed seams / taping – Extra insulation
  • Chest zip entry – Better seal vs back zip
  • Hooded wetsuits – Reduces heat loss significantly

4mm vs 5mm Wetsuits

  • 4mm wetsuits – Best for spring, autumn and milder conditions
  • 5mm wetsuits – Designed for winter and cold water

If you’re surfing in UK winter conditions, a 5mm wetsuit is the safer and more comfortable choice.

5mm Wetsuit FAQs

Is a 5mm wetsuit too warm?

Not for UK winter. In water temperatures below 12°C, a 5mm wetsuit is often necessary to stay comfortable.

Do I need a hood with a 5mm wetsuit?

For colder winter conditions, a hooded wetsuit is highly recommended as a large amount of heat is lost through the head.

What’s the difference between 5/4mm and 5/4/3mm wetsuits?

5/4/3mm wetsuits offer slightly more flexibility in the arms and shoulders, making them better for performance surfing.
