How do Wetsuits Work and How They Are Made?

A wetsuit is a specialized garment designed to provide thermal insulation to the wearer while immersed in water. A wetsuit traps a thin layer of water between the neoprene material and the wearer’s skin. 

How do Wetsuits Work and How They Are Made?

T divers, surfers, and other water sports enthusiasts commonly use wetsuits to maintain body heat and protect against the cold. This article will explore the science behind wetsuits, their construction, and how do wetsuits work. Let’s see how do wetsuits work with mechanisms.

What Are Wetsuits?

A wetsuit is a specialized garment designed to provide thermal insulation to the wearer while immersed in water. Wetsuits are made from a material called neoprene, which is a synthetic rubber. 

Neoprene is an excellent insulator because it contains tiny gas bubbles within its structure. These bubbles trap and retain a layer of water against the skin, which is then heated by the body, creating an insulating barrier between the skin and the cold water.

How Do Wetsuits Work?

Wetsuits are typically made of multiple layers of neoprene foam. The foam is flexible, durable, and provides excellent insulation. The thickness of the neoprene varies depending on the water temperature and the intended use of the wetsuit. Thicker neoprene offers more insulation but can limit flexibility.

A wetsuit traps a thin layer of water between the neoprene material and the wearer’s skin. The body heat warms up this layer of water and forms a barrier against the surrounding colder water, helping to keep the wearer warm.

Layers in a Typical Wetsuit And How They Work?

By incorporating these layers, wetsuits offer insulation, protection, and comfort to divers, surfers, and other water sports enthusiasts. It allows them to stay warm and enjoy their underwater experiences while minimizing the risk of hypothermia.

  1. Comfort Layer

The comfort layer is designed to keep the wearer’s skin from direct contact with water. It is usually made of a smooth and soft material that prevents discomfort and chafing during water activities.

  1. Heat-Reflective Layer

Following the comfort layer, the heat-reflective layer plays a crucial role in retaining the body’s heat and keeping the wearer warm underwater. This layer incorporates materials that reflect the body’s heat toward the skin. While not all wetsuits may have this specific feature, choosing a high-quality wetsuit that provides effective heat retention is advisable.

  1. Neoprene Layer

The neoprene layer is a fundamental component of a wetsuit and is responsible for maintaining a stable temperature while submerged in water. This layer is typically made of neoprene, synthetic rubber with excellent insulation properties. The thickness and elasticity of the neoprene layer may vary depending on the specific wetsuit and its intended use.

  1. Outer Layer

The outer layer serves as a protective barrier for the wetsuit, safeguarding it against wear and tear, abrasions, and damage caused by environmental factors. It is designed to be durable and robust, enhancing the longevity of the wetsuit. The outer layer is often made of solid material, such as nylon or synthetic fabrics, that can withstand the rigors of water activities.

  1. Trapped Water Layer

The primary mechanism by which wetsuits keep the wearer warm is by trapping a thin layer of water between the suit and the skin. When the wearer enters the water, a small amount enters the suit through the neck, wrist, and ankle openings. This water is trapped inside the suit, creating a thin layer that quickly warms up to body temperature.

Characteristics of WetSuits

Here are the characteristics of wetsuits.

  • Fit and Design

Wetsuits are designed to fit snugly against the wearer’s body to minimize the amount of water flowing in and out. A tight fit prevents water from constantly flushing through the suit, which would decrease its insulating properties. Wetsuits often have zippers or velcro fastenings at the back to facilitate easy entry and exit.

  • Hydrodynamics

In addition to insulation, wetsuits can improve hydrodynamics by reducing drag in the water. The smooth neoprene surface reduces friction, allowing the wearer to move more efficiently through the water.

  • Care and Maintenance

To ensure the longevity of a wetsuit, proper care is essential. After each use, it should be rinsed with fresh water to remove salt, sand, and other debris. It should be dried away from direct sunlight to prevent damage to the neoprene. Additionally, wetsuits should be stored flat or hung on a wide hanger to maintain shape.

  • Thickness and Water Temperature

The neoprene thickness in wetsuits varies depending on the water temperature. Thicker suits provide more insulation and are suitable for colder water, while thinner cases are used in warmer conditions. Some wetsuits have different thicknesses in different areas to provide extra insulation in areas more prone to heat loss, such as the chest and back.

  • Wetsuit Insulation

Wetsuit insulation is crucial in maintaining warmth for divers and swimmers when submerged in cold water. One of the latest advancements in wetsuit technology is the incorporation of Omnired technology, which harnesses the power of infrared radiation to enhance insulation properties.

The OmniRed Swimsuit

The Omni Red swimsuit is designed with thermo-reactive minerals that can convert the body’s heat into thermal energy. This innovative feature enables the wetsuit to reflect the thermal energy to the wearer, ensuring a comfortable and warm experience underwater.

How do Wetsuits Work and How They Are Made?

Extensive research conducted by leading scientists has demonstrated that Omnired technology surpasses other insulation technologies available in the industry. The wetsuit provides warmth, quick-dry properties, and flexibility, enhancing the overall comfort for divers and swimmers.

The application of Omnired technology provides several benefits to users. 

 Benefits Of OmniRed Swimsuit

  • Firstly, it promotes better circulation in the body through infrared. 
  • Improved blood flow circulation leads to elevated oxygen levels, resulting in a feeling of warmth and increased stamina. 
  • Furthermore, the enhanced circulation facilitated by Omnired technology contributes to faster recovery and better overall health. 
  • Increased cell function within the body promotes improved stamina and endurance, aiding quicker recovery.


Water has higher thermal conductivity than air, transferring heat from the body more rapidly. However, the trapped water in a wetsuit forms an insulating layer that minimizes heat loss from the body to the surrounding water, thus helping to maintain a comfortable body temperature.

Neoprene is a popular wetsuit material because of its insulating properties and flexibility. It is resistant to degradation by oils, sunlight, and chemicals found in water, making it suitable for prolonged exposure to aquatic environments.

No, wetsuits are not entirely waterproof. They allow a small amount of water to enter, creating an insulating layer against the skin. However, they are designed to minimize water circulation to maintain warmth.

Final Verdict

Wetsuits are vital for water enthusiasts, providing thermal insulation and protection against cold water. By utilizing the insulating properties of neoprene and the trapped water layer, wetsuits help maintain the wearer’s body temperature, allowing them to enjoy their activities in various water temperatures. 

We have explored the science behind wetsuits, their construction, and how they work above. So, proper fit, construction, and care are essential for maximizing the effectiveness and lifespan of a wetsuit.
