Imagine humans exploring underwater with the wrong suit. They would come out feeling frozen. The right diving suit makes a major difference in how confident and comfortable you feel in the water. Many people see the suit as a fancy costume, but it actually protects your skin, supports smooth movement, and helps you enjoy the experience without worrying about how you will survive.
This article explains what a diving suit is, outlines its different types, and helps you decide which one fits your adventure. It also shares key points to consider before buying one, helping you avoid spending money on gear you may not need.
What is a diving suit?
A diving suit is protective gear that shields divers from cold temperatures, water pressure, and other underwater hazards. Many traditional Indonesian divers still lack proper knowledge about diving suits, and reports show that nearly 80% of them are unaware of the preparation, clothing, or what gear is required before a dive.
Diving suits were created to make underwater exploration safer. Early divers often died from freezing temperatures, dangerous pressure, and marine hazards, making proper protection essential. Inventors developed the first true diving suit in the 18th–19th century, and in 1830 introduced the standard diving dress. This heavy, weighted suit equipped with a metal helmet connected to an air pump allowed divers to breathe and stay underwater for longer.
As underwater research expanded, the demand for better protection grew. Modern suits have become more advanced, and they offer temperature control, pressure resistance, buoyancy support, and protect the skin.
Different types of diving suits
A diving suit is not one-size-fits-all. It is built differently for different water conditions and diving purposes. Recreational divers use different suits as they spend a shorter time underwater. Research or long-duration dives use specialised gear designed to support extended underwater stays.
This section will give you an idea about the different diving costumes, so that next time, when you decide to go underwater, you are fully prepared. You will also get more information about how you can go beneath the surface with the suits and how they help divers in different ways.
Wetsuit
Divers most commonly use this suit for recreational underwater exploration. Its thin neoprene layer traps water, and the body warms that water to create insulation. Recreational divers can usually go around 30 to 40 metres underwater. Beyond that, the suit becomes ineffective because the neoprene compresses under water.
Drysuit
This diving suit is designed to keep you completely dry under the water. The watertight seals on wrists, neck, and ankles help in preventing water from entering. A drysuit is mainly used in extremely cold underwater conditions, and the divers can wear additional layers of insulation to keep warm. More of this diving gear is perfect for going deeper because it provides better thermal protection and better buoyancy control, which is why divers need more training and skills in using it.
Dive Skin
This is a very lightweight and thin diving suit made from Lycra or spandex. It has very little thermal protection, but it works very well for divers in warm waters. With this, divers cannot go deeper, and they can only explore around 18 to 30 meters. However, if they go beyond without proper insulation, they are at risk of hypothermia.
Atmospheric diving suit (ADS)
This is a rigid, armour-like suit used only for professional sea explorations. It helps in maintaining the pressure of the body under the suit, even in extreme conditions. The ADS eliminates divers from repeated decompression stops and protects them from crushing pressure. This gear cannot be used by everyone; only trained and research professionals can use it with proper knowledge.
Key things to remember while choosing a diving suit
Buying a diving suit is not like purchasing clothes; you cannot buy anything based on its looks or simply because it fits you. This is a matter of safety, so you need to be very particular while choosing one. This section will highlight a few key points that you need to keep in mind before you decide which gear you want. Below are the points:
- Know the water temperature – This is the most important factor; you should know exactly where you will be diving. Cold waters require a suit of 5 to 7 mm thickness. Whereas, tropical waters only need a suit 2 to 3 mm thick wetsuit.
- Choose the right fit – Your diving suit should fit you properly without restricting your movement. You also don’t want a gear that is too loose for water to pass in and out.
- Decide your diving type – Different diving activities also influence the gear that you need. For instance, if it is for recreational purposes, a standard wetsuit is enough.
- Look for the material quality – You might want to go for a higher quality material that is more stretchable, durable, and has more insulation. For frequent divers, investing in a diving suit with premium materials is a good idea for long-term comfort.
- Check your zippers and the tapes – Strong glues and tapes prevent water leakage. You should also have good-quality zippers for your back and chest, to make it easier for you to wear the costume.
- Keep safety as your priority – Don’t choose a diving suit simply because it is visually appealing. Make sure your costume has additional safety features such as UV protection, scratch-resistant panels, and pre-installed kneepads. It will help you stay safe from different underwater hazards.
