Wetsuits for wild swimming

Wild swimming is growing in popularity, and it's easy to see why. Beyond the physical benefits, it has a positive impact on mental health. Swimming also offers a unique way to connect with nature and explore new areas. Swim-specific wetsuits act like a second skin, providing the protection and performance you need.

If you’re new to wild swimming or considering an upgrade, this guide will help you choose a wetsuit.

Why choose a swimming wetsuit

If you're planning to swim outdoors in the UK, investing in a wetsuit is a smart move. While a multi-purpose surf wetsuit might seem enough, a swimming wetsuit can improve your performance in races, timed events, and even your stroke efficiency. 

The key benefits of using a swimming wetsuit:
  

  • Warmth: Essential for open water swimming, especially during colder months.  

  • Buoyancy: Wetsuits provide extra floatation, helping to improve your swimming position. Some suits offer more buoyancy in the legs, aiding technique.  

  • Speed: Designed to reduce drag in the water, swim-specific wetsuits enhance your efficiency and speed.  

  • Protection: In the ocean, particularly during jellyfish season, a wetsuit offers a layer of protection.  

The difference between swimming and multi-purpose wetsuits

Multi-Purpose wetsuits:  

  • Made with thicker neoprene for durability and stretch  

  • Varying thickness across the chest, legs, and arms, with a focus on warmth  

  • Reinforced in high-wear areas like the knees  

  • Typically uses double-lined neoprene, which is durable but thicker and less smooth  



Swimming wetsuits:  

  • Made with thinner neoprene for better movement  

  • Prioritise flexibility and stretch for an unrestricted swim stroke  

  • Vary thickness strategically to aid buoyancy and swimming technique  

  • Use single-lined neoprene for a smoother finish, improving speed and efficiency  

  • Features a low neckline to avoid neck restriction while swimming

Material

Swimming wetsuits use neoprene differently from surf wetsuits. They typically feature single-lined neoprene, which has a nylon lining on the inside only. This construction protects against wind chill while allowing water to run off easily, keeping you lighter and more streamlined.

Wetsuits are constructed with either flatlock or glued, blind-stitched seams. Flatlock seams, found in cheaper wetsuits, are best suited for summer as they allow some water penetration. Glued blind-stitched seams, found in higher-end suits, are watertight, flexible, and durable, making them ideal for cold water use.

Thickness

The thickness of neoprene affects a wetsuit's warmth, durability, flexibility, and buoyancy. While thicker neoprene provides more warmth, swim wetsuits use varying thicknesses across different panels to optimise buoyancy and movement. Thinner neoprene is used in the arms and shoulders for better flexibility, while slightly thicker neoprene at the hips helps your body sit higher in the water. If you tend to drag your feet while swimming, look for a wetsuit with thicker neoprene in the legs to help lift your feet and improve your technique.

How should your wetsuit fit?

Fitting tips

  • Ensure the wetsuit pulls in around your lower back without leaving a big gap. If there’s excess fabric, the suit is too big and may allow water in.  

  • With your arms parallel to the ground, the wetsuit should be close to your armpits with slight folds on top of the shoulders.  

  • When you extend your arms in front and cross them at the wrists, check for a minimal gap at the neckline.  

  • Remember, a correctly fitted wetsuit may feel slightly uncomfortable on land, but it will work seamlessly with your body once you're in the water.
