Buying Your First Swimming Wetsuit?

Jeff from the Wetsuit Centre gives you some on advice on buying your first swimming or triathlon wetsuit. Along with our favourite wetsuits.

Choosing the Right Swimming Wetsuit

The best swimming wetsuit depends on water temperature, swim frequency and experience level. Unlike surf wetsuits, swimming wetsuits are designed for improved shoulder mobility, buoyancy and efficient movement in open water.

  • Beginner swimmers – buoyancy-focused suits can help improve body position and confidence.
  • Cold water swimming – choose thicker neoprene or thermal linings for extra warmth.
  • Regular open water swimmers – prioritise comfort, flexibility and durability.
  • Event training or racing – explore specialist Triathlon Wetsuits designed for speed and transitions.

The right wetsuit helps you stay warmer, conserve energy and enjoy longer sessions outdoors.

Key Features to Look For in a Swimming Wetsuit

When choosing a swimming wetsuit, focus on the features that improve comfort, confidence and efficiency in open water:

  • Flexible shoulders – Helps support a natural swim stroke with less fatigue.
  • Buoyancy support – Can improve body position and reduce drag.
  • Thermal warmth – Neoprene thickness and linings help in cooler water.
  • Comfortable fit – A snug fit helps retain warmth without restricting movement.
  • Durable construction – Important for regular lake, river and sea swimming.
  • High visibility details – Bright colours or panels can help you stay more visible outdoors.

The right combination of features can make outdoor swimming more comfortable, efficient and enjoyable.

Why Not Use a Surf Wetsuit for Swimming?

  • Restricts shoulder movement
  • Lacks buoyancy support
  • Creates drag in the water

Swimming Wetsuit FAQs

Why Not Use A Surf Wetsuit For Swimming?

Surf wetsuits are designed for paddling and board sports, while swimming wetsuits are made for front-crawl movement, better shoulder flexibility and improved body position in the water. This usually makes them more comfortable and efficient for open water swimming.

What thickness wetsuit should I choose for swimming in the UK?

Many swimmers choose 3mm wetsuits for summer and 4–5mm suits for cooler spring, autumn and winter conditions. The right thickness depends on water temperature, tolerance to cold and swim duration.

Do I need a wetsuit for wild swimming?

A wetsuit is not always essential in warm summer conditions, but many wild swimmers choose one for warmth, buoyancy and comfort in cooler UK water.

Which accessories help in cold water?

Cold water swimmers often use neoprene gloves, socks, caps or hoods, plus tow floats for visibility and safety.
