FAQs

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. Wetsuits gives extra lift, providing the swimmer with buoyancy, which makes it easier for the swimmer to stay afloat.

A wetsuit’s buoyancy keeps the swimmer closer to the surface of the water, and this means that they spend more energy moving forward and less energy staying above water. The design and materials of a wetsuit allow 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 is 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 and the distance of the swim. If you’re going to be swimming for 100 yards or more, then a wetsuit is highly recommended.

How much warmer does a wetsuit keep you?

The thickness of the wetsuit is what influences its thermal qualities. But there are trade-offs in flexibility. The thicker the wetsuit is, the less flexible it becomes. If the temperature of the water is 68 degrees, then you’ll 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 50 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 also need to consider your own sensitivity to cold, and weather conditions on the day.

Before you enter a triathlon, whether a local sprint event or an Ironman, familiarize yourself with the rules for wetsuits.

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

As technology advances, materials 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 as well. 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 provides.
