What is a wetsuit for?

A wetsuit helps to insulate and provide some warmth when swimming in cold water. It prevents your limbs and muscles from going numb in very cold water. The wetsuit gives extra lift, providing the swimmer with buoyancy, which makes it easier for the swimmer to stay afloat.

The buoyancy of the wetsuit keeps the swimmer closer to the surface of the water and this means that they spend less time and energy to avoid sinking. The design and materials of the wetsuit allows the swimmer to move faster with less resistance in the water.

When should you wear a wetsuit?

If the water is between 50 to 65 degrees Fahrenheit, then a wetsuit would be highly recommended. You wouldn’t need a wetsuit if the temperature is 84 degrees Fahrenheit or more. There are other factors to consider, such as the climate or altitude you’re at and the distance of the swim. If you’re going to be swimming for 100 yards or more, then a wetsuit would be highly recommended.

How much warmer does a wetsuit keep you?

The thickness of the wetsuit is what influences its flexibility and thermal qualities. This means that the thicker the wetsuit is, the less flexible it becomes. If the temperature of the water is 68 degrees Fahrenheit then you’d be able to use a 1 mm thick wetsuit, whereas you’d use a 3 to 4 mm thick wetsuit for swimming in temperatures of 48,2 to 57 degrees Fahrenheit.

This could change depending on where you are in the world, as you’d need to take climate and altitude into consideration. You’d also need to consider your own sensitivity to cold and weather conditions on the day.

Before you enter a triathlon or even Ironman you may want to familiarize yourself with the rules for wetsuits.

What do I get if I invest a bit more money into my wetsuit?

As technology advances, the material and designs of wetsuits also advance. When you buy your wetsuit, you need to take into consideration your swimming technique, how frequently you’ll be using the wetsuit and what your goals are.

Then you want to make sure that the wetsuit that you get has plenty of flexibility in the shoulders, as this will provide a better range of motion for your swim stroke. You’ll also want to make sure that the wetsuit offers better buoyancy and that you’re not rolling too much on one side.

You may want to have a look at the thermal properties of the wetsuit. This will let you know what temperatures you can swim in, as well as give you an idea as to how much insulation the wetsuit would be able to provide.
