What To Wear Under A Wetsuit

Experienced scuba divers know exactly what wetsuits to use. Taking into account the type and thickness of the wetsuit, the location of the zip, and how the wetsuit fits. And all these factors can easily be learned by a novice.

But another consideration to consider when you’re starting out is what to wear under a wetsuit? Find out more here…

The Reasons for Wearing Undergarments

What do you wear under a wetsuit? This frequently asked question can be answered simply – it’s entirely up to you. Deciding what to wear depends on the environment you plan to dive in. And the temperature of the water.

Opinions are diversified but there are certain factors you should take into account:

Renting a wetsuit means that other scuba divers have worn it before. So, hygiene will play a part in your decision to wear lycra dive shorts or a bathing suit rather than nothing at all.

Wetsuits can make skin sore and chaffed in areas where there’s a lot of movement against the skin – such as your neck and armpits. As well as your undergarments you could apply anti-chafing gel or cream to minimise any wetsuit rash.

Extra layers keep your body warmer in colder temperatures whether you’re in or out of the water. Thin layers can provide additional insulation without the need for a thicker wetsuit that may be restrictive.

Some undergarments have UV protection making them ideal for different temperatures during a single dive. And they give an extra defence against scrapes, stings, cuts, and bites.

Changing in public places is never simple as wetsuits can quickly become hard to take off. Wearing a bathing suit will nullify any decency issues!

Undergarment Choices

So, what do you wear underneath a wetsuit? Look at a range of solutions here…

Rash Guards

Rash guards and compression shirts for men are ideal for a first layer providing protection from wetsuit chafing. There’s a choice of short or long sleeves – and the lightweight material makes them ideal for scuba diving.

Ladies may prefer sleeveless tops that give greater freedom around the arms and shoulders. These vests are made from fine, quick-drying, lightweight materials that are recommended for layering under diving wetsuits.

Diving Shorts

Neoprene diving shorts are light and buoyant but also thick enough to give added warmth. As well as helping to get easy access in and out of your wetsuit. Super-stretch foam neoprene rubber that doesn’t wrinkle is an ideal choice and suitable for men and women.

Elastic and smooth fitting dive shorts specially designed for ladies are insulating and absorbent. And lightweight options are flexible and comfortable.


A full-body jumpsuit will help keep you warm as it provides entire coverage. Ultra-thin neoprene gives natural insulation. And is comfortable without being bulky. Flattering cuts and pull tabs on the back zip are added features.

Full-body jumpsuits for ladies offer natural insulation alongside a lightweight fabric. Optional extras feature thermal-bonded knee pads, lycra trimmed wrist and ankle seals, and fast drying.

Diving Briefs and Swimsuits

When you dive in warm waters and want the protection without the added layers an alternative option is a lightweight and comfortable diving brief. A mix of lycra and nylon fibre ensures a stretchy, chlorine-resistant fit that stays put and won’t sag.

High-performance swimwear is ideal for scuba diving as the one-piece swimsuit has flat-lock stitching, non-slip straps, and a front lining for comfort with the least coverage.
