Tips On Buying Your First Women’s Wetsuit

Martina from Sisters Of Stoke, a local women’s surfing group, gives you some advice on buying your first womens wetsuit.

Choosing the Right Women’s 4mm Wetsuit

A 4mm wetsuit is a versatile choice for transitional seasons, offering more warmth than a 3mm wetsuit while maintaining flexibility for active use.

  • 12–17°C water temperatures – Ideal for spring and autumn
  • 4/3mm construction – Warm core with flexible arms
  • Longer sessions – Better heat retention than thinner suits
  • Multi-purpose use – Suitable for surfing, SUP and swimming

If you’re often in the water outside peak summer, a 4mm wetsuit is a reliable all-round option.

Why Choose a Women’s 4/3mm Wetsuit?

A 4/3mm wetsuit offers a balance between warmth and movement, making it one of the most versatile thicknesses available.

  • Warmer than a 3mm for cooler conditions
  • More flexible than thicker winter suits
  • Ideal for changing UK weather
  • Suitable for a wide range of water sports

It’s the perfect step up when a summer wetsuit no longer feels warm enough.

Key Features to Look For

When choosing a women’s 4mm wetsuit, focus on features that improve warmth without compromising comfort:

  • 4/3mm neoprene – Insulation where it matters most
  • Thermal lining – Helps retain body heat in cooler water
  • Glued & blind stitched seams – Reduces water entry
  • Stretch panels – Maintains flexibility through shoulders and arms
  • Chest zip entry – Improves seal and warmth

These features make a noticeable difference in cooler conditions.
