What is a neoprene wetsuit?

Scubapro Definition Overall 5mm

A neoprene wetsuit is made of neoprene. In technical fields, neoprene is known as chloroprene rubber or polychloroprene. At the molecular level, the material consists mainly of chlorine and hydrogen atoms. Production begins with a chemical reaction between chloroprene and other solutions.

The result of this reaction is flakes. These flakes can be further processed. In order to transform the solid synthetic rubber flakes into elastic rubber, it needs vulcanization. After the vulcanization the molecules can no longer move, the end result is elastic and will always spring back to its original shape.

In order to be able to sell neoprene as a fabric, the right and left side of a neoprene sheet are covered with fabrics, these can also be printed with colors or patterns.

Men and Women Difference

In many Scuba Diving Equipment Parts there is no difference between Men and Women however there is a big one in Neoprene Wetsuit cuts. Women feel usually much faster cold than men so it’s a better Idea to buy a thicker wetsuit if you are a frosty.

My next guide will be all about women Wetsuits. Don’t want to miss it? Then subscribe to our free newsletter.

Insulation ability of neoprene wetsuit

First of all, we have to know that water dissipates body heat 25 times faster than air, so you cannot survive forever even in water at 25° C and the colder the water, the faster you lose your body heat.

Neoprene has excellent insulation properties that is due to the fact that a lot of air is trapped in the neoprene, which, as we know, has very good insulation.

Thickness of a neoprene wetsuit

The thicker the neoprene fabric, the better the insulation from the cold water.

Mostly for very cold water with 12° C and colder or for ice diving and long dives in them, you’d use a dry suit.

Neoprene wetsuits from approx. 7mm thickness can be used for cold water diving (12° C and colder), but dry suits are recommended. This also includes neoprene gloves, hoods and booties.

Long neoprene wetsuits in 3-5mm thickness are usually used for waters with a water temperature of more than 18° C.

Shorties are neoprene wetsuits with short arms and half-length legs, these are mostly 3mm thick and they are used for water temperatures from 25° C upwards.

Buoyancy and thickness of the neoprene wetsuits

Weight and thickness of Wetsuit
Weight and thickness of Wetsuit

The neoprene thickness of the suit affects the buoyancy control, as thicker material creates more static buoyancy. This buoyancy has to be compensated with lead weights. To make matters worse, the neoprene itself is compressed by the water pressure increasing with depth, so that the buoyancy decreases with increasing ambient pressure – i.e. increasing water depth. Since the weight of the lead remains constant, the downforce increases with increasing depth, which has to be compensated for by a buoyancy compensator (BCD).

How does a neoprene wetsuit work?

Many believe that you don’t get wet in a neoprene wetsuit. This is only true in a dry suit.

Wetsuit function
Function of a neoprene wetsuit
and a semidry wetsuit

In all other diving suits you get wet. The water that has entered the wetsuit remains in the suit because the ends of a neoprene wetsuit are provided with cuffs and the thin layer of water is thus heated up by the body heat.

That is why it is so important to have a neoprene wetsuit that is skin-tight because the less water penetrates, the less the body has to heat the water entered up and the longer you stay warm. Depending on the suit, this water layer is exchanged faster or slower (water circulation).

Types of neoprene wetsuits


Cressi Shorty

Is the simplest version of the neoprene wetsuit. As the word shorty suggests, they have short arms and legs and are only effective in protecting the core temperature of the body.

This can be worn in tropical areas with water temperatures of 25° C and more. Mostly in the common thicknesses of 1.5-3mm available. and also obviously the cheapest version of all of them.

Neoprene Wetsuit

Is a Neoprene wetsuit with long arms and legs where cuffs are sewn on so that the water stays in the suit and is not exchanged as quickly. Usually comes in thicknesses between 3-7mm

Semi-Dry Neopren Wetsuit

These suits don’t just get you “half-wet”. These neoprene wetsuits have smooth neoprene sealing lips on the arms, legs and neck. With the higher quality semi-dry neoprene wetsuits, the zipper is also underlaid with a cuff or sealing lip. Which causes the water to run into the suit but no longer come out of the suit or relatively slowly through e.g. Movement while scuba diving water is exchanged. This makes the suit very comfortable for colder waters for long or several dives per day. Most semi-dry wetsuits come in thicknesses between 5-7mm.

Dry Suit

Drysuit function
Funktion eines Trockentauchanzugs

There are several types of drysuits and the topic is very large as buoyancy control is not only done with the BCD but also has to be done with the suit itself. I’m not going to go into this type of suit too much, though.

Even if you have successfully completed a diving course and buy a dry suit, you should try it out in the swimming pool or in shallow water or even better take a course. Most international diving organizations offer dry suit diving courses. Because there are certain things with this suit that you have to pay attention to and practice in order not to be in danger underwater!

Some will still remember: When James Bond in “Goldfinger” takes off his wetsuit (dry suit) and wears a tuxedo underneath that is completely dry and yes it would work.

Dry suits are designed for diving in very cold water, for commercial underwater work, and for sewage diving.

The dry suit, is a one-piece suit made of water- and gas-tight material. Today these are made from trilaminate membranes of synthetic plastics or neoprene.

The advantage of the dry suit is that the diver hardly ever comes into contact with water and, when properly filled with an insulating gas, like air it is better protected from the cold than in any other diving suits. The dry suit is usually sealed with a cuff at the neck and wrist and the boots are permantly attached. It has a water and gas-tight zipper on the back or chest for getting in and out. In addition, textile protective clothing against the cold is worn under the suit.



The main zipper on a neoprene wetsuit can be on the back as well as on the front, vertical, horizontal or diagonal. For the shorties and neoprene wetsuits, these are normal coarse zippers mostly made of plastic because they don’t rust. In the case of a dry suit, this must be zipper which is gas and waterproof so that no water penetrates. The semi-dry wetsuits have both wet and dry zipper versions.

All zippers on the neoprene wetsuits are underlaid with a smooth neoprene sealing lip as this is more comfortable and the pure zipper does not cause irritation of the skin.

Thicker long wet and semi dry neoprene wetsuits with zippers on the arms and legs make it easier to get into the suit.

Insider tip:

If the neoprene wetsuit has no zippers and it is very difficult for you to put the suit on, you can put a plastic bag over your hand or foot before getting into the suit. The neoprene slides much better then. The alternative is to mix a little dish washing liquid and water and spray it on the arm or leg.

Protection against injury and nettles


Neoprene wetsuits are not only worn to protect against cooling down of the body temperature, but also to protect against injuries such as jellyfish and their nettles.

Or if you accidentally roam along a rock face. Shipwrecks are also a good example with their sharp edges

One piece or two piece

Two piece neoprene Wetsuit

A one-piece is a neoprene diving suit that consists of one part. Here different thicknesses of neoprene can be sewn together so that the one-piece is, for example, a 3mm thick wetsuit on the arms and legs and a 5mm thick neoprene wetsuit on the core of the body.

A two-piece is two separate pieces of clothing, a high-cut or bib shorts (called “Long John”) and a long-sleeved jacket, usually with an attached hood, so you have a thick double suit at the core of your body.

Some two-piece neoprene wetsuits only consist of pants and a vest, but they are also much less warm.

Ice vest

Eisweste Neopren

One-piece suits sometimes come with a separate ice vest to be able to dive with this suit in very cold waters.

This ice vest is worn over the normal suit.

But you can also buy them individually.

Care and cleaning

After a dive in salt water, fresh water or swimming pool, you should always rinse the neoprene suits with fresh water and then dry them. However, getting these dry inside can take time. Turning it onto the left and right works wonders.

The zips of the neoprene suits should be creamed with candle wax every now and then, as this extends the service life and makes it easier to close and open.

Theoretically, women neoprene wetsuits can also be cleaned in a washing machine, but you must ensure that you select a gentle program, such as a wool program. The temperature should not be higher than 30°C. Neoprene should never be spun or dried in a tumble dryer.
