Choosing the Right 5/4mm Wetsuit

A 5/4mm wetsuit is essential for staying warm and comfortable during UK winter conditions, when water temperatures drop and wind chill increases.

7–12°C water temperatures – Ideal for UK winter surfing
5/4mm construction – Maximum warmth in the body with flexibility in the arms
Cold weather sessions – Designed to retain heat in harsh conditions
Longer time in the water – Reduces fatigue caused by cold exposure

If you’re surfing through winter, a 5/4mm wetsuit is one of the most important pieces of kit you’ll own.

Why Choose a 5/4mm Wetsuit?

5/4mm wetsuits are designed specifically for cold water performance, offering the highest level of insulation before moving into fully hooded suits.

Ideal for regular cold water surfers

For consistent winter surfing, a 5/4mm wetsuit provides the warmth you need without excessive restriction.

Key Features to Look For

When choosing a winter wetsuit, warmth and sealing are critical:

Thermal linings – Trap heat and improve comfort
Glued & blind-stitched seams – Minimise water entry
Taped seams – Extra protection in extreme conditions
Chest zip entry – Reduces flushing and improves warmth
Wind-resistant panels – Protect against cold winds

These features make a huge difference when surfing in winter conditions.
