Best Wetsuits for Outdoor Swimming

Best Wetsuits for Outdoor Swimming In The UK

Swimming in open water can be an exhilarating experience, but it can also be challenging. One of the most important pieces of equipment for any open water swimmer or triathlete is a wetsuit. Not only can a wetsuit help you stay warm in colder water, but it can also improve your body position in the water and help you swim more efficiently. In this article, we will explore the best wetsuits for outdoor swimming, wild swimming and triathlon training and what to look for when choosing one.

Neoprene Open-Water Swimming Wetsuit

What Makes Neoprene Material Ideal for Wetsuits?

Neoprene is the material of choice for wetsuits due to its insulating properties and flexibility. The material is able to trap a layer of water between the skin and the suit, which is then warmed by body heat, providing a layer of insulation. Additionally, its flexibility allows for ease of movement in the water. How does a wetsuit work? Read our guide.

What to Look for in an Outdoor Swimming Wetsuit? 

Neoprene Thickness

One of the most important factors to consider when choosing a wetsuit for open water swimming is the thickness of the neoprene material. A thicker wetsuit will keep you warmer in colder water, but it may also restrict your range of motion. Conversely, a thinner wetsuit may be more flexible, but it may not provide enough insulation in colder water. The solution is a wetsuit made up of different neoprene panels of varying thicknesses. For example a 4/3/2 wetsuit.

What is a 4/3/2 neoprene wetsuit?

A 4/3/2 neoprene wetsuit refers to the thickness of the neoprene material used in different parts of the wetsuit. The first number (4) refers to the thickness of the neoprene used in the torso and upper legs, the second number (3) refers to the thickness of the neoprene used in the arms and lower legs, and the third number (2) refers to the thickness of the neoprene used in areas that require more flexibility, such as around the shoulders and underarms.

So, a 4/3/2 wetsuit is a wetsuit with varying thicknesses of neoprene material in different areas of the wetsuit to provide different levels of warmth and flexibility. The thicker neoprene in the torso and upper legs provides more insulation and buoyancy, while the thinner neoprene in the arms and lower legs allows for greater flexibility and ease of movement. The even thinner neoprene in the areas that require more flexibility allows for maximum mobility and range of motion.

This type of wetsuit is commonly used in swimming wetsuits as the thicker neoprene provides more warmth, buoyancy and insulation whilst the thinner neoprene provides flexibility and range of motion. 

Buoyancy distribution:

The buoyancy should be distributed in a way that helps your swimming style. For example, if you’re a weaker swimmer, you may benefit from a wetsuit with more buoyancy in the chest and torso area. The right amount of buoyancy is essential for a good swimming wetsuit. It should provide enough lift to keep you in a good swimming position, but not so much that it hinders your movement. A wetsuit with thicker material around the hips and thighs can help keep your lower body in the optimal position.

Flexibility:

A good wetsuit should allow for a full range of motion in your arms, shoulders, and legs. Look for a wetsuit that is made of flexible and stretchy neoprene and has panels designed to allow for easy movement.

Fit

A swimming wetsuit that fits well is crucial for comfort, flexibility, and performance. Make sure to measure yourself accurately and follow the manufacturer’s sizing chart. You want it to fit like a second skin! When trying on a wetsuit, it should feel snug but not too tight. Make sure the suit fits your body properly, leaving no gaps or folds in the material. Additionally, ensure that the wetsuit is comfortable to move around in and allows for natural swimming movement.

Ease of putting on and taking off:

Look for a wetsuit with a zipper that’s easy to operate and a design that allows you to quickly and easily take it off when finished swimming. Getting warm quickly is very important after outdoor swimming. Check our changing robe guide and our changing mat guides.

Comfort:

It’s important to find a wetsuit that fits comfortably and doesn’t chafe or rub, however, this is most likely unattainable (read our guide to chaffing). Look for a wetsuit with a comfortable collar, seams that are placed strategically, and a flexible zip.

Visibility:

Brightly coloured wetsuits or wetsuits with reflective panels can help make you more visible in open water, increasing your safety. Also, consider swimming with a tow float! What is the most visible water safety colour? Read our guide.

Full Wetsuit vs. Sleeveless Wetsuit

Another consideration when choosing a wetsuit is whether to opt for a full wetsuit or a sleeveless wetsuit. A full wetsuit covers your entire body and provides more insulation, while a sleeveless wetsuit allows for a greater range of movement in your arms. The choice ultimately comes down to personal preference and the temperature of the water you’ll be swimming in.

Durability:

A triathlon or swimming wetsuit can be a significant investment, so you want it to last. Look for a wetsuit with high-quality neoprene and sturdy zippers. A wetsuit with reinforced seams will also be more durable. However, due to the nature of these swimming wetsuits, most are far more fragile than a standard wetsuit that you may wear for SUP, surfing, etc. This is due to the neoprene only being coated on one side with nylon, exposing the outer surface for its hydrodynamic properties. This sacrifice for performance makes the suite more suitable for nail tares and general tares. A lot of triathlon wetsuit wearers use gloves or bags to put on the suit without damaging it. 

Hydrodynamics:

Hydrodynamics refers to the wetsuit’s ability to reduce drag and increase speed in the water. Look for a wetsuit with a smooth (smooth skin) and streamlined design that reduces resistance and drag, allowing you to move more efficiently through the water.

Smoothskin:

Smoothskin neoprene is a type of neoprene that has a smooth, almost rubber-like surface that repels water and reduces drag. It is often used in the wetsuit’s outer layer or in areas that require maximum hydrodynamics, such as the arms and shoulders. Wetsuits with smooth skin neoprene can be more expensive than those without, but they offer better performance and faster swimming times. They are also more delicate and require more careful handling to prevent damage to the smooth outer layer.

Construction and Stitching.

There are two main methods of wetsuit construction: stitching and glueing.

Stitching involves sewing together the panels of neoprene using a special stitch that prevents water from seeping through the seams. There are two types of stitching commonly used in wetsuit construction: flatlock stitching and blind stitching.

Flatlock stitching is commonly used in entry-level wetsuits and involves overlapping the panels of neoprene and sewing them together using a flat seam. This type of stitching is less effective at preventing water from seeping through the seams, but it is more flexible and less expensive.

Blind stitching, also known as glued and blind-stitched (GBS), involves glueing the panels of neoprene together and then stitching them together from the inside using a curved needle. This type of stitching is more effective at preventing water from seeping through the seams, but it is also more expensive and less flexible than flatlock stitching.

Glueing involves bonding the panels of neoprene together using a special glue or adhesive. Glueing is often used in conjunction with stitching to create a more watertight seal. It is commonly used in high-end wetsuits and in areas that require maximum flexibility and hydrodynamics, such as the shoulders and underarms.

In addition to stitching and glueing, wetsuits may also feature taped seams or liquid seals to provide additional protection against water seepage. Taped seams involve applying a strip of waterproof tape to the inside of the seam, while liquid seals involve applying a liquid adhesive to the seam.

Overall, the type of construction used in a triathlon wetsuit will affect its durability, comfort, and overall performance. Consider the type of stitching or glueing used, as well as any additional features like taped seams or liquid seals when choosing a wetsuit that best meets your needs and budget.

Cost:

Swimming wetsuits are some of the most expensive wetsuits available on the market. These can cost from £130 up to £1000 depending on the brand and the features. The high end is only recommended for those who are actively competing at the highest levels.
