Shopping Guide

Whether as a sport or leisure, diving is a unique practice. The sensations, the challenges, the connection with nature, these elements make a combination difficult to find in another activity. But there are dangers too, and cautions to be taken.

One of them is the choice of the ideal diving suit, the most suitable for your body and your type of diving, even for the type and temperature of the water. We set up the Purchasing Guide below to provide the information you need to make this choice the best possible.

Wet, semi-dry or dry wetsuit?

More than modalities, there are several conditions in which dives are carried out. For each of them, there is a specific set of techniques and equipment. Among them, of course, the diving suit.

There are three main types of clothing, for the three most common conditions: so-called wet clothing, semi-dry clothing and dry clothing. The names, as you may have noticed, indicate the level of water penetration inside the clothing.

Wet clothes are those that allow water to fully penetrate inside. Made of neoprene, its protection is based on the thickness of your fabric. Between two and seven millimeters, the thickness must be inversely proportional to the water temperature, or at least according to the thermal sensitivity of the user.

The ideal is to use wet clothes with a thickness of 2 or 3mm in waters with temperatures above 24ºC. Between 15º and 23ºC, at least 5mm. From there down, it is practically mandatory to wear a suit with 6mm or more.

The semi-dry suit allows a partial entry of water, which is even indicated before diving so as not to create excess air inside the suit and cause possible injuries. Made of neoprene and often with “nylon” finish, it is a suit suitable for low temperatures, approximately up to 14ºC.

The great innovation of this costume is in its zipper, the so-called dry zipper, which, positioned laterally or even on the back, prevents water from entering during the dive.

Dry clothes are those that do not allow any water penetration, since they are used for extremely cold waters. Because of this, its use is very specific, with changes in the diver’s fluctuation and even with mechanisms to inflate and deflate. There are preparatory courses just for this costume.

How to wash a diving suit?

Wetsuits are expensive equipment, and knowing how to wash them properly is just as important as knowing how to wear them. As they are clothes in contact with water, their hygiene can cause some confusion. But in just five steps you can do the whole process properly:

    • Wash immediately after use in cold, fresh water. Many users take their clothes off in the shower;
    • No machine! The thing is to soak it in a bucket and rub it gently;
    • Use a special cleaner , suitable for wetsuits or neoprene;
    • Let the clothes dry in shade , and inside out. It is best to use a hanger suitable for this costume, or at least a heavier one;
    • Don’t forget to lubricate the zipper after drying!

Wetsuit or Wetsuit?

Wetsuits and wetsuits are very similar products, with the same material, design and the same basic premise. This can confuse someone by doing a search on online stores and web pages.

As similar as they may be, there are some key points that differentiate them, such as, to begin with, their use. Diving suits , as the name says, are made specifically for this activity, while wetsuits are more versatile, used by surfers, triathletes, swimmers, among others.

For this reason, wetsuits and wetsuits have different characteristics, especially with regard to the usefulness of innovations and technologies. Diving suits focus on thermal protection and buoyancy, while wetsuits focus on athletic performance, that is, flexibility and endurance.

In the material, both suits use and abuse the neoprene. The wetsuit usually combines it with high density nylon, while wetsuits use it with rubber in the composition.

What to wear under a wetsuit?

As they are tight, the diving suits give the impression of the comfort of a second skin type suit, which does not happen. Its process of dressing and removal can be somewhat complicated, apart from the cold that many users can feel, even wearing the thickest suits.

So, many people use T-shirts, which can be simple, like a second skin or even a more “soft” neoprene, to adjust comfort and facilitate the entire strip-and-put of clothes. Even more common is the use of swimwear, swimsuits and bikinis, for a similar effect in the most delicate areas.

How much does a wetsuit cost?

As you saw in this Buying Guide, wetsuits are highly specific equipment, with quality materials and technologies appropriate for your proposed activity. The value of the models, therefore, is high.

You can find more basic costumes starting at R $ 250, while professional clothes cost around R $ 4000 and R $ 5000.


Purchase Criteria: Comparing and choosing your wetsuit

If all the preparation for a dive was not enough – location, transport, date – it is also necessary to pay attention to the clothes that will be used. Lucky for you, at least in this last part, you have help. In the list below, we show only what matters, and what you should note before choosing your model and proceeding with your purchase.

  • Dive type
  • Composition
  • Thickness
  • Design

Dive type

Adapting your clothes to the type of diving practiced is not only a matter of selection, but of safety. Starting with the correct thermal insulation, to protect your body from hypothermia, a very common reaction in dives, even in the hottest waters.

There is also the question of cost-benefit and investment. So, for example, to buy clothes for extremely cold and deep waters if you are only going to do a snorkel in more shallow waters (up to 4 meters), isn’t it?


The composition of the wetsuit fabric is an extremely important point for your choice. The materials must have some degree of impermeability, but mainly thermal insulation and, of course, comfort, after all, we are talking about clothes, not armor!

If it is not neoprene or lycra, do not pay attention.

If the model is not neoprene or lycra, do not pay attention. Lycra is best used for more shallow dives, and neoprene is quite versatile. The greater the difficulty of diving, reinforcements of nylon and rubber are also welcome


If you are concentrating your search on the internet, it is very likely that already in the first results you will find products with measurements in millimeters in your description, between 2mm and 7mm, mainly. These numbers are literally the thickness of the clothes.

The logic in this case is the same as for any cold clothing: the lower the temperature, the thicker the clothing must be. In colder waters, any suit less than 6mm will be harmful.

In quieter dives, the thickness already becomes a more personal issue, of its thermal sensation.


The design of the clothing is a great starting point for your choice. I explain: you can choose, for example, a suit with shorts and short sleeves, and then choose the model with the necessary specifications for your type of diving.

It is also worth paying attention to the functional details of the design of the clothes, such as the zipper, decisive for the entry of water into the suit or not, and also to the seams, if they are resistant, if they are reinforced and especially if they are not open.
