How Do Wetsuits Work? – 4 Best Types Of Wetsuits To Choose From

How Do Wetsuits Work


Wetsuits are an essential piece of equipment for water sports enthusiasts, providing warmth, comfort, and protection from the elements. Whether you’re surfing, diving, or paddleboarding, a good wetsuit can make all the difference. But have you ever wondered how wetsuits work? What makes them so effective at keeping you warm in cold water? In this article, we’ll take a deep dive into wetsuit technology and explore the science behind these incredible pieces of gear.

How Do Wetsuits Work?

Wetsuits work by trapping a thin layer of water between your skin and the suit. Your body heat warms up this layer of water, creating a barrier of warmth that insulates you from the cold water outside. The wetsuit material then works to prevent this warm water from escaping, keeping you warm and comfortable in even the coldest conditions.

Wetsuit Construction

Wetsuits are typically made from a neoprene material, which is a synthetic rubber that is both flexible and waterproof. This material is then lined with a soft, warm lining, such as fleece or polypropylene. The neoprene material is usually between 2-5mm thick, depending on the type of wetsuit and the conditions you’ll be using it in.

The seams of a wetsuit are also an important factor in its performance. Seams can be glued, blind-stitched, or liquid-sealed to prevent water from seeping in through the gaps. Some wetsuits also feature reinforced knees and elbows for added durability.

Types of Wetsuits

There are several types of wetsuits, each designed for different water temperatures and activities. The most common types include:


These wetsuits cover your entire body and are the best option for cold water or extreme conditions.

Spring Suits

These wetsuits cover your torso and arms but leave your legs exposed. They are ideal for mild to warm water temperatures.


These wetsuits cover your torso and upper legs and are perfect for warmer water temperatures.


Unlike wetsuits, dry suits are completely waterproof and do not rely on a layer of water to keep you warm. They are ideal for extremely cold water or diving.

How to Choose the Right Wetsuit

Choosing the right wetsuit is essential for your comfort and safety in the water. When selecting a wetsuit, consider the following factors:

  1. Water Temperature – The colder the water, the thicker the wetsuit you’ll need.
  2. Activity – Different activities require different types of wetsuits. For example, surfing suits are designed differently than diving ones.
  3. Fit – A properly fitting wetsuit should be snug but not too tight. Make sure you try on several sizes before making your final selection.


Q: How do I clean and care for my wetsuit? A: Rinse your wetsuit with fresh water after each use and hang it to dry in a shaded area. Avoid exposing it to direct sunlight or heat sources.

Q: Can I wear a wetsuit in warm water? A: Yes, you can wear a wetsuit in warm water, but it may be uncomfortable. Consider a shorty wetsuit or a rash guard instead.

Q: Do wetsuits prevent hypothermia? A: They can help prevent hypothermia by keeping

you warm in cold water. However, it’s important to note that wetsuits are not a guarantee against hypothermia and other safety precautions should still be taken.

Q: How do I put on a wetsuit? A: To put on a wetsuit, start with the legs and work your way up. Pull the suit up over your hips, making sure it’s snug but not too tight. Then, pull the arms up and zip up the back. Finally, adjust the collar and cuffs for a proper fit.


Wetsuits are a vital piece of equipment for anyone who enjoys water sports. Whether you’re a beginner or an experienced athlete, understanding how they work can help you choose the right one for your needs and stay safe and comfortable in the water. By trapping a layer of water between your skin and the suit, they provide a barrier of warmth that insulates you from the cold water outside. With the right fit and thickness, a good wetsuit can keep you warm and comfortable in even the coldest conditions, allowing you to enjoy your favorite water sports year-round.
