What is the Difference Between Wetsuit vs Drysuit?

If you are confused about whether to purchase a wetsuit or drysuit for diving, then this article is for you. Here we are going to briefly explain the difference between the wetsuits vs drysuits.

Before purchasing an exposure suit, you must need to know what is the difference between wetsuit vs drysuit? So keep reading carefully until the end.

The Wetsuit and Its Functionality

A wetsuit offers thermal protection to the divers. Basically, the wetsuit works in accordance with the principle that the body of the diver is the source of heat.

It is made up of closed-cell foams. These foams are filled with a multitude of tiny gas bubbles organized in the structure. So this wetsuit can produce enough heat underwater.

As soon as you get into the water, the material lets a thin layer of water flow through the suit. Apart from that, it perfectly fills the space between the inner part of the material and your body.

With your body temperature, this layer increases the water temperature. And this warmness will help you to continue diving with comfort.

When it comes to talking about the design of diving suits, it is mentionable that these are designed in such a way that it fits your body properly.

If this exposure suit won’t fit you, it will allow the water to get into the spaces between your skin and the suit. In this case, your body may lose the energy to heat the water, so it makes no sense to be thermal.

The wetsuit should also be thick enough to hold the temperature of the water of your diving area. In fact, the performance of a wetsuit varies depending on the thickness. With a thicker and more insulated wetsuit, you will get more protection from the cold water. On the other hand, you may get more benefits from a thicker suit in warm water.   

Anyway, it is mentionable that the condition of the body varies from person to person. So surely the different person will get the different output. If you want to dive in tropical waters, then you can use a lycra wetsuit.

Or else, you will need a 2 mm thicker wetsuit or more. Sometimes you need to wear a 6mm thicker suit, especially, when you will dive in the cold water.

The Drysuit and Its Functionality

A drysuit is mainly responsible for keeping you dry while diving in the water. In other words, it prevents you from getting wet. The drysuit may be made from a variety of materials, vulcanized rubber, foam neoprene, heavy duty nylon to mention a few.

In fact, it is completely sealed with the combination of neck seal, wrist seal, and waterproof zipper to prevent entering the water.

Drysuits are looser than those of its wetsuit counterparts. So you can wear the regular clothes. You may even be allowed to wear some insulated layers underneath the drysuit.

The drysuit utilizes inflator valves which will allow you to fill the gas. So you can go deeper. It also utilizes exhaust valves that allow you to vent air during upturn.  

The inflator valve is similar in function to the power inflator on a buoyancy compensator vest and is often situated in the middle of the chest on the suit.

The inflator valve and the power inflator are the same in terms of functionality. And the suit holds the power inflator in the inner part of the chest.  

The drysuit requires certain functionality to maintain neutral floatage. You may need to practice to get used to diving with the drysuit. You also can have training to be an expert. In fact, we strongly recommend getting effective training from an expert diver to gain experience.  

The Comparison Between Wetsuits and Drysuits

If you still have confusion  which one would be perfect for you, then these basic differences between wetsuits and drysuits will help you to decide. So let’s explore the differences.

Thermal Insulation

The wetsuit utilizes a layer of warmed water so that the divers can dive with comfort. On the other hand, the drysuit utilizes the layer of air, and these are entirely sealed to prevent you from getting wet.

The benefit of the wetsuits over the drysuit is that it will help you stay warm. Because the water can conduct heat more than twenty times faster than air.

Both suits will allow you to wear clothes underneath. But the drysuit will offer more advantage here over the wetsuit as they loosely fit your body.  So you will get more thermal insulation with the drysuit.

Portability and Ease of use

Wetsuits often enable quick and comfortable movement under water thanks to its better fitting. With more materials, the drysuits are heavier than those of wetsuits.

So these can cause resistance when moving underwater. And it may take more time to wear a drysuit compared to its wetsuit counterpart.

Longevity and Cost-effectiveness

With the complex design and construction, the drysuit will cost more than that of wetsuit. So it offers more functionality to the diver. It may even be used in a variety of environments. 

Even though the drysuit is more expensive, it will be more cost-effective. You may raise the question of how? Well, a high-quality drysuit will last longer. In fact, it can last more than a decade if you maintain and take care of it properly. 

Demand

There are a lot of brands out there that come with the drysuits. Owing to the durable construction,  With the emergence of more brands and the availability of newer materials, a top-rated entry-level drysuit will cost more than a heavy duty wetsuit.

If you consider the long term value, then the drysuit will be the winner over the wetsuit. The best thing is that the drysuit offers more value and pace.
