What to Wear Under a Wetsuit: Your Guide to Comfort and Functionality

Wetsuits are necessary for sports like scuba diving, surfing, and snorkelling. But have you ever thought about what's under that snug neoprene? Putting on the right clothes under your costume can make you more comfortable and help you do better. It's easy to make the right decisions after reading this article.

In this article, we will help you to choose the right undergarments for a wetsuit and what to wear for any gender.

Choosing the Right Undergarments for Your Wetsuit

  1. Material Choices

The first thing to think about when choosing underwear for a jacket is the material. Fabrics made of polyester or nylon are great because they dry quickly and don't hold on to water, which can make you feel colder and make burning more likely. But you should stay away from cotton because it soaks up and holds on to water, making it heavy and uncomfortable when it's wet.

  1. Choosing Garments Based on Activities

What kind of activity you want to do will also affect what underwear you choose. For things like swimming and scuba diving, you should wear a thin rash guard or a dive skin. These not only keep you warmer, but they also make it easier to put on and take off your wetsuit. When you go surfing, you should wear a swimsuit or a rash guard made just for surfing because they are made to handle rough water and a lot of movement.

  1. Focusing on Comfort and Fit

The clothing you put on under your costume should fit close but not too tight. This keeps the cloth from bunching up, which can be uncomfortable and irritate the skin when you move. It's better to wear clothes with few seams because they are less likely to rub against your skin. If you are going to be in the water for a long time, you should think about getting underwear with seamless or flat seams.

  1. Personal Preference Matters

Some surfers and divers like to wear nothing under their wetsuits so they can move around more easily and comfortably. This is an individual choice that may depend on things like the warmth of the water and how easily you get chafing.

What Can You Wear Under a Wetsuit

When picking out what to wear under a wetsuit, you should think about how it will work, how comfortable it is, and the weather where you'll be doing water activities. Each type of clothing has a specific job to do and can improve your experience by meeting different needs, like keeping you warm, making it easier to move around, or keeping you from burning.

For Men

  1. Rash Guards

When guys wear wetsuits, rash guards are a must-have piece of clothing. They add an extra layer of protection that keeps you from getting burning and rashes from the wetsuit material. As there are both short- and long-sleeved rash guards, men can choose the style that best fits their needs in terms of sun protection and warmth.

  1. Swim Briefs or Trunks

A lot of guys like to wear swim trunks or briefs under their wetsuits. The materials used to make these dry quickly and don't soak up water, so they don't stick to the skin. If you don't want your swim shorts to bunch up under your wetsuit, make sure they fit well.

  1. Neoprene Shorts

Neoprene shorts are a great choice for guys who want to stay warmer, especially in colder water. These give you an extra layer of warmth without being too bulky to move around in.

For Women

  1. Swimsuits

Women who wear wetsuits often choose one-piece swimsuits or two-piece bikinis made of synthetic materials. The purpose of these choices is to stay in place and withstand the physical demands of activities like diving and surfing without soaking up excess water.

  1. Sports Bras and Compression Shorts

Some women like to wear a sports bra under a wetsuit to give them extra support, especially when they are doing high-impact water sports. For extra ease and to avoid chafing, you can also wear compression shorts. These are great for tasks that need you to move around a lot.

  1. Women’s Rash Guards

Like rash guards for men, rash guards for women come in different sleeve lengths and are made to fit women's bodies. They do the same thing, which is to keep you from burning and keep you warm. There are some rash guards for women that have built-in support, so you may not need a separate sports bra.

Unisex and Gender-Neutral 

  1. Dive Skins

The thin, stretchy material used to make dive skins is great for wearing under wetsuits because it makes putting on the wetsuit easier by adding a smooth layer. They come in mixed styles that are good for both men and women, protect against UV rays, and make you a little warmer.

  1. Thermal Layers

You can stay warm while diving or surfing in very cold water by wearing thermal layers under your wetsuits. Most of the time, these aren't gender-specific and are more about usefulness and warmth than fit.


  1. Can I wear regular underwear under my wetsuit? 

Regular underwear shouldn't be worn because they are usually made of cotton and soak up water, which can make you feel uncomfortable and cause itching. Choose synthetic clothes that dry quickly instead.

  1. Are there specific products designed for wearing under a wetsuit? 

If you want to do that, you can use items like wetsuit liners, dive skins, and rash guards. The materials used to make these keep you warm and make it easier to put on and take off a costume.

  1. Is it necessary to wear anything under a wetsuit for thermal protection? 

Wearing a thin layer like a rash guard or a dive skin isn't always required, but it can help keep you warmer, especially in colder water.


It's important to choose the right clothes to wear under your jacket to keep you comfortable, mobile, and protected from the weather. You should always think about the material, fit, and needs of your water exercise when choosing underwear. You can have the best time on your water activities if you have the right gear.
