Do Wetsuits Keep You Warm?

A wetsuit is a garment that has been designed to provide thermal protection while in water.

In most cases, it is made of foamed neoprene material, and it is worn by surfers, divers, windsurfers, canoeists, and anyone involved in water sports or other water-related activities.

As the name implies, it is designed to provide thermal insulation and protection from impact, ultraviolet exposure, and the effects of marine life.

Additionally, it also provides you with floating capabilities.

In order for neoprene foam to be effective as an insulation material, it has to contain bubbles of gas that reduce the ability of the material to conduct heat.

In addition to providing buoyancy in water, bubbles give the wetsuit a low density, allowing it to float on water.

It is important that you have a wetsuit when going into any lake or sea as it will provide you with the support that you need.

This guide will explain everything you need to know about a wetsuit and why you should own one.

Are They Warm?

Absolutely is the answer.

One of their main duties is keeping you warm so that you stay comfortable, and the thermal material plays a key role in keeping you warm.

In spite of this, believe it or not it will not actually stop you from getting hypothermia, so do take care.

How They Keep You Warm

It is not just a question of whether wetsuits keep you warm that we get asked, it is also a question of whether they keep you dry as well.

If a wetsuit is able to keep you warm then it must be able to keep you dry as well, although it shouldn’t be assumed that it will.

In truth, that couldn’t be farther from the truth, as wetsuits don’t provide any protection against the elements.

That may seem confusing but it actually isn’t at all!

Neoprene makes it possible for you to wear a wetsuit while staying warm, especially when combined with water and your own body heat.

Wetsuits trap water between your skin and the wetsuit, which gets warmed by body heat as soon as you get into the water no matter the Fahrenheit.

Your body ultimately feels warm from this layer. Even though you may feel warm once you get moving in the water while wearing a wetsuit, the shock of getting into the water may hit you at first.

Is The Thickness Of A Wetsuit Important?

If you are out there scuba diving or snorkeling, you will certainly appreciate a 1mm wetsuit top or a 2mm shorty springsuit.

Nevertheless, even at 68 degrees F, your body will only be comfortably warm with those thicknesses

Generally, the lower the water temperature, the thicker the wetsuit you’ll need.

This makes it pretty easy to understand for anyone looking to get a wetsuit and what they are going to be using it for.

If you plan on going in some frozen lake you best have a thick wetsuit otherwise you will be in big trouble!

It is simply not possible to survive in those winter conditions in a 2mm or 3mm thick wetsuit.

You should consider wearing a 5/4mm, 5/4/3mm, or even a 6/5mm wetsuit instead.

Neoprene has a high degree of protection and warmth, so the thicker it is, the better.

A difference is also made by seams. There is always the possibility for water to seep through flatlock, standard seams, which is why they are often found on wetsuits for warmer waters.

It is your best defense against cold water seeping into the wetsuit if the seams are sealed & taped or even sealed & external liquid taped.

As a result, you will be able to stay in the water for a longer period of time since you’ll be warmer.
