Wetsuit Diving

If you plan to dive long or deep, you will need something to protect you from the cold water. It is easy to underestimate how dangerous the cold can be. If your body gets hypothermic from cold water, permanent damage can occur. You need a protective suit to make sure this doesn’t happen to you. In addition, you need to worry about other dangers under water. Can a wetsuit offer protection from all these dangers when diving?

What Does a Wetsuit Do?

A wetsuit has two functions. Firstly, a wetsuit is supposed to prevent water from entering the suit and to keep the diver warm and thus protect them from hypothermia. Hypothermia already occurs when the body reaches a core temperature of 35 degrees and the first symptoms quickly become noticeable.

A wetsuit cannot fully fulfill the first function. There is no wetsuit that can keep out 100% of the water. But this is not even necessary. There even is an advantage that can come from a small amount of water in the wetsuit.
The second function of a wetsuit is to keep the diver warm. The suit does this by preventing the diver's body warmth from escaping. This way, the body warmth stays inside the suit and the body does not have to use new energy to stay warm. As already mentioned, some water will always get into the wetsuit. This small amount of water is warmed by the diver's body warmth, forming an additional protective layer against the cold water on the outside.

What Else Does a Protective Suit Have To Do?

A protective suit for diving does not only have to protect you from the sun, but there are many other diving hazards that a good diving suit can mitigate. Pay attention to the following criteria if you want to make that you have a good protective suit.

Protection From Sharp Objects and the Sun

One of these things is sharp objects at the bottom of the water. Neoprene is a very resistant material, as it is not brittle but stretchy. There are very few objects on the bottom that can penetrate a high-quality wetsuit. It is important that you protect yourself from injuries as it can be very difficult to help you underwater if you are seriously injured.

A nice side effect of a wetsuit is that it also offers protection from the sun. A wetsuit covers almost the entire body, so no harmful UV radiation can reach these areas. Therefore, you don't have to worry about sunburn or UV rays when wearing a wetsuit out of the water.


A good protective suit has to fit snugly against the diver's skin. This way, the body heat can be utilised as best as possible. If your protective suit for diving is too big or too small for you, you won't be able to move properly underwater. This could lead to you injuring yourself or having less fun while diving.

This is one advantage of a wetsuit. The material is extremely stretchy and fits very close to your skin without being uncomfortable. This is why many water sports enthusiasts like to use wetsuits.

Finish and Durability

Finish and durability are two other important criteria for a good protective suit for diving. Neoprene fulfils these two criteria very well.

The finish is important as zips and seams must have been placed in a way that ensures that they do not interfere with your diving. Incorrectly or poorly placed seams and zips can rub badly against your skin because wetsuits have a very tight fit.

Fortunately, there are many processing techniques in wetsuits that allow manufacturers to use safe seams and zips.
The durability of the suit is closely related to the finish. Neoprene has a very long lifespan due to the material's stretchability and cut resistance. This means that a high quality wetsuit can last a very long time and accompany you for a very long time in water sports.

So Are Wetsuits Suitable for Diving?

If you summarise all the important criteria for a protective suit, you will come to the conclusion that a neoprene suit is very well suited for diving.

A wetsuit can protect the diver's body from hypothermia, block harmful UV rays, is resistant to cuts, is stretchable and has a long life thanks to good workmanship. If you want to start diving, you can confidently use a wetsuit to protect yourself underwater.
