Choosing the Right 4/3mm Wetsuit

A 4/3mm wetsuit is the ideal choice for cooler conditions when a summer wetsuit isn’t warm enough, but a full winter suit would feel too restrictive.

  • 10–15°C water temperatures – Ideal for UK autumn and milder winter days
  • 4/3mm construction – Extra warmth in the body, flexibility in the arms
  • Versatile performance – Suitable for surfing, paddleboarding and more
  • Longer sessions in cooler water – Retains heat without excessive bulk

For many surfers, a 4/3mm wetsuit is the perfect transition suit between summer and winter.

Why Choose a 4/3mm Wetsuit?

4/3mm wetsuits provide the perfect step up in warmth from 3mm suits, without the thickness and restriction of winter wetsuits.

If you surf regularly outside peak summer, a 4/3mm wetsuit is an essential part of your setup.

Key Features to Look For

When choosing a 4/3mm wetsuit, focus on features that maximise warmth without sacrificing flexibility:

  • Thermal linings – Retain heat in colder water
  • Chest zip entry – Reduces water flushing and improves warmth
  • Glued & blind-stitched seams – Minimise water entry
  • Stretch neoprene panels – Maintain paddling flexibility
  • Sealed seams or taping – Improve insulation in windy conditions

These features make a big difference when temperatures drop.

4mm Wetsuit FAQs

Is a 4/3mm wetsuit warm enough for UK winter?

A 4/3mm wetsuit is ideal for autumn and milder winter days, but for the coldest months you may need a 5mm or hooded wetsuit.

What is the difference between 4mm and 4/3mm wetsuits?

A 4/3mm wetsuit uses 4mm neoprene in the core for warmth and 3mm in the arms for flexibility, making it the most popular option.

Should I choose 3mm or 4/3mm?

If you’re surfing in cooler conditions or outside peak summer, a 4/3mm wetsuit offers significantly more warmth.
