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 cold-water wetsuits currently available so that you can stay nice and warm while completing your cold water swim.

10 Best wetsuits for swimming in cold water pinterest

Coldwater is generally classified as water in the temperature range of 75℉ or 23℃ 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 placed 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.

The wetsuits we are looking at in this article will mostly include triathlon or open water wetsuits since these are the most ideal for swimming performance. There may, however, also be a suit or two that isn’t necessarily a triathlon or open water wetsuit, but I decided to include it if it still allows for good swimming performance while providing you with ideal insulation from cold water.
