If you’ve decided to challenge the arctic waters of your local cold water lake or pool, then you better make sure that you have the right wetsuit to get the job done. In today’s article, we will be taking a look at some of the best wetsuits for swimming in cold water currently available so that you can stay nice and warm while completing your cold water swim.

Cold water is generally classified as water in the temperature range of 70℉ or 21℃ and below. Different cold water wetsuits are used for different water temperatures with the fabric becoming thicker and thicker as the water becomes colder. 

Wetsuits are designed to keep you warm in the water by insulating you in cold water temperatures. This is generally done by utilizing a material called neoprene, which is a rubbery, water-resistant fabric that will trap a thin layer of water around your skin, allowing it to heat up through your body heat and keep you warm in icy waters.

Water temperature and wetsuit thickness.

Before choosing your wetsuit you should have a rough idea of the water temperature you are looking to swim in. This will help you to decide on the ideal thickness of your wetsuit to keep you warm in the cold water.

Below is a quick chart I put together so that you can see what the thickness of your suit needs to be, but don’t worry the wetsuits in this guide are also marked under the temperature ranges they are designed for. This is just to give you some added guidance on what you’re looking at.

For those of you who aren’t completely sure what temperature the water is you are looking to swim in, I recommend purchasing a suit out of the 62-68℉/16-20℃ range or to be safe out of the 58-63℉/14-17℃ rage. These are the most common cold water temperatures. 

I, however, also recommend checking online to see if you can find the water temperature range for the area where you want to swim to help you make the best possible decision when purchasing your wetsuit.

43°-52℉ / 6°-11℃5/4mm – 5/4/3mmFullsuitSealed and taped
42℉ / 5℃ and below6/5mm – 6/5/4mmFullsuitSealed and taped

Understanding the thickness of your wetsuit is quite simple. For example, for a 5/4/3mm wetsuit, it would mean that the torso is 5mm thick, the legs 4mm, and the arms 3mm. The order is universal for all wetsuits. If a wetsuit only has 2 values, for example, 6/5mm, it would mean the torso is 6mm and the arms and legs are both 5mm.

You may also choose to purchase additional equipment to keep you warm like boots, gloves, and a hood. This may be required for very cold water.

How to choose a wetsuit for swimming in cold water.

Now that we’ve covered some of the best wetsuits for swimming in cold water, let’s take a quick look at some markers to look at when purchasing your cold water swimming wetsuit.

1. Water tempreture.

Picking a wetsuit that will be able to support the cold water temperature range that you want to swim in is very important. Generally, wetsuits covering the 50°-80°F (10°-26°C) temperature range will be more than sufficient for the majority of swimmers.

If you are crazy enough to swim in temperatures lower than this I recommend going with the Blueseventy Thermal Reaction wetsuit. This is a popular option and provides great performance and insulation. It’s rated for swimming in water temperatures between 42°-70°F (6°-21°C), giving you plenty of room to play with.

2. Wetsuit purpose.

What do you want to use your wetsuit for? Are you planning on competing in a competitive triathlon or open water race? Or are you just looking to train in some colder water temperatures?

If you want to use your wetsuit for training and competition, then we recommend going with one of the top of the range wetsuits or at least with a mid-range wetsuit at the very least. These suits feature higher and better specifications and will give you a bit more of an advantage over your competitors.

If on the other hand, you are just looking for a training wetsuit then we recommend going with a mid-range or budget option since you don’t really require the best specifications. My recommended option would be anything between the TYR Hurricane Cat 1, Orca RS1, Or Synergy 5/3mm wetsuit.

3. Wetsuit design.

There are 2 main types of wetsuit designs to pick from. The first being the fullsuit design and the second the sleeveless design. Both designs are good options but there are some differences that you may want to take into consideration when choosing your cold water wetsuit.

Sleeveless wetsuits are ideal for cold water temperatures between 62°-68℉ (16°-20℃) and above. This makes them a good option if you live in a warmer region and want to be able to use your wetsuit year-round. They also offer more range of motion and feel a bit more flexible in the water.

Fullsuit wetsuits, on the other hand, are recommended for water tempertures below 60℉ (15°C). They provide better insulation and aren’t quite as flexibile as sleeveless suits but will still provide optimal range of motion for most swimmers.

4. Wetsuit fabric.

As you’ve probably noticed throughout the article, different wetsuits are designed from different fabrics. Although all of the wetsuits feature some type of neoprene fabric design, there are, in fact, differences between these neoprene fabrics.

Yamamoto neoprene is the highest-quality neoprene fabric and is ideal for swimming performance. There are different variations of Yamamoto neoprene indicated by its cell value. The higher the cell value, the higher the quality of the fabric.

5. Wetsuit Zipper.

Most of the wetsuits feature sealed zippers which are ideal for insulating you in cold water. For temperatures under 50℉ (10°C) you’ll, however, require a sealed and taped zipper design as this provides more insulation.

Swimming in cold water can be a challenging experience and making sure that you have the right wetsuit for getting the job done is a critical part of the process. Something to keep in mind for colder water temperatures is that you might also require gloves and booties to stay warm, not just a wetsuit. 

So, with that said, what are you waiting for? Get out there and go swim!
