1. What is a Deep Sea Diving Suit?

A deep sea diving suit is a garment typically worn during water activities like surfing, diving, windsurfing, canoeing, waterskiing, and others. Deep sea diving suits are normally made by a material called neoprene. Neoprene is a synthetic rubber made from the polymerization of chloroprene. It is known for maintaining chemical stability and flexibility over a wide range of temperatures.

What Makes Them Useful?

Deep sea diving suits are useful in a number of different respects. They are excellent thermal insulators, meaning they are highly effective at trapping body heat. They are also very buoyant and resistant to abrasion. They are able to accomplish all this because of tiny bubbles of gas imbedded into the material. These air bubbles make it more difficult for the suit to conduct heat away from the body. They also make the suit less dense, which creates the buoyancy effect.

2. What Are the Different Types of Deep Sea Diving Suits?

There are three main types of diving suits: the wetsuit, the semi-dry suit, and the drysuit.

Wetsuits

Wetsuits are the most common kind of deep sea diving suit. They typically range from 0.5 and 8 mm and are usually made from neoprene, the rubber polymer mentioned above. Wetsuits trap water between themselves and the wearer’s body. It warms up this thin layer of water, creating an insulating thermal barrier over your skin.

Wetsuits come in a wide variety of models. Depending on the manufacturer, you can choose models based on the water temperatures they are suited for, whether you need an entire suit or just a top or bottom, or whether it is intended for men, women, or children. Some kinds close in the back while others close in the front. Since these are more popular than the other types of diving suits, you are likely to find a much wider selection of suits to choose from.

Semi-Dry

The semi-dry suit is a wetsuit with minimal to no water trapped between the material and the wearer’s skin. Semi-dry suits are designed with seals around the neck, wrists, and ankles. They also have watertight horizontal back closures. What all of this means is that because there is little or no water circulation within the suit, there is also less energy loss. As a result, a semi-dry suit is highly effective at retaining heat, and they are particularly popular among divers in waters of between 10 and 20 degrees Celsius.

The slight drawback to the semi-dry suit is that it is more difficult to put one on. Putting one on will require the help of a partner once it comes time to zip up the back.

Dry Suit

Finally, the dry suit is a unique type of diving suit that allows you to wear clothing underneath. That layer of clothing, the dry suit’s material, and an adjustable inner layer of air work together to keep you warm. They are ideal for use in cold waters or during long rebreather dives. The downsides to the dry suit are that it is less durable, requires more maintenance, and is less affordable.

When picking out your deep sea diving suit, be sure to consider its thickness. Wetsuits in particular come in a wide variety of thicknesses. They can generally be broken down into 7 mm wetsuits, 5 mm wetsuits, and 3 mm wetsuits. 7 mm wetsuits are best suited for diving in waters around 50 to 60 degrees Fahrenheit. 5 mm wetsuits are best in the 60 to 70 degrees Fahrenheit range. 3 mm wetsuits are best for the 70 to 85 degrees Fahrenheit range.

3. What Are Benefits of Wearing a Deep Sea Diving Suit?

You might be wondering if you can save yourself a bit of cash and just go diving in your regular swimwear. The answer is a resounding “no.”

The first benefit of wearing one is thermal insulation. Wearing a deep sea diving suit will keep you warm and prevent you from getting hypothermia. Do not make the mistake of assuming hypothermia is a worst-case scenario you only need to worry about during deep dives into cold waters. Even if the water is in the high 80’s, your core body temperature can drop, preventing a major health risk.

The second benefit is physical protection. When you are underwater, the temperature is just one danger to contend with. You may also encounter physical hazards, like sharp rocks, coral, jellyfish debris, and more. Wearing a suit will provide an essential layer of protection.

The third benefit is increased buoyancy. As mentioned above, these suits are designed to hold tiny air bubbles within their material. These bubbles decrease their density, making it easier for you to float.

4. What Is Hypothermia?

Hypothermia is a very real threat to every diver. It is a medical emergency during which your body loses heat faster than it can create it. The ideal body temperature is around 98.6 degrees Fahrenheit, or 37 degrees Celsius. Hypothermia occurs when your body temperature drops below 95 degrees Fahrenheit, or 35 degrees Celsius.

Hypothermia prevents your heart, nervous system, and other essential organs from working properly. It can eventually cause death by shutting down your heart and respiratory system. When you are immersed in cold water, you are particularly vulnerable to hypothermia. Symptoms of hypothermia Include:

  • ​Shivering
  • ​Slurred speech
  • ​Weak pulse
  • ​Decreased coordination
  • ​Shallow breathing
  • ​Energy loss
  • ​Confusion
  • ​Loss of consciousness

The danger of hypothermia is that once you begin experiencing symptoms, it becomes incredibly difficult to notice them, as they come on very gradually. That is why you should always dive in groups. If you or someone you know experiences hypothermia, you should immediately take steps to remove yourself or your colleague from the water and raise the body temperature back to normal.

5. Where Can You Buy a Deep Sea Diving Suit?

You can find one in many sporting goods stores, especially outdoor sporting goods stores. Of course, you can also buy one from one of the many stores dedicated to selling diving gear. These stores are particularly easy to find near the beach. Like most things, suits are also highly available online on sites like Amazon.
