Additional insulation and protection

The main reason why divers wear underwear under their wetsuits is that the extra layers keep their bodies much warmer in colder temperatures above and below water. Instead of wearing a very thick suit that restricts movement and consumes energy faster, experienced divers wear thin layers underneath to additionally isolate the body.

In addition to the cold or the heat of the water, the temperature of the air and the wind above the water is an important factor that must be taken into account when deciding whether to wear underwear with your wet suit or not. Divers often have different temperatures during a single dive, so it is important to choose the right material and type of underwear to protect your body at a comfortable temperature during your dive.


Many divers prefer to undress under their wetsuits, but it can sometimes be uncomfortable to say nothing of the pain caused by the constant rubbing of the skin against the inside of the wetsuit. After wearing a wetsuit for a long time, some divers find that their skin begins to rub and feel sore, which is why divers prefer to wear underwear under the suit.

It’s not really hygienic, especially if the person who wore it before you does not care about skincare. You can also keep in mind that some people pee in their overalls, which is, even more, an incentive to put on underwear.
