Wetsuits are essential gear for many water sports enthusiasts, from surfers to triathletes. They provide insulation, buoyancy, and protection from the elements, enhancing the overall experience in cold waters. But how exactly do wetsuits work? We’ll explore how wetsuits keep you warm, whether they keep you dry, and offer a beginner’s guide to choosing the right swimming wetsuit.
How Do Wetsuits Keep You Warm?
Wetsuits are designed to trap a thin layer of water between the suit and your skin. Here’s how this process keeps you warm:
1. Insulation through Water Layer
When you enter cold water, your body temperature will begin to drop. A wetsuit is made from neoprene, a material that has insulating properties. As you swim, the water that seeps into the wetsuit warms up due to your body heat. This creates a barrier that slows down the rate of heat loss. The layer of water trapped inside the wetsuit is crucial; while it may feel cold initially, your body quickly warms it, providing insulation.
2. Reduced Heat Loss
Wetsuits are designed to fit snugly against the skin, which helps to minimize water movement within the suit. This close fit prevents excessive cold water from rushing in and washing away the warm layer. The thickness of the neoprene also contributes to its insulation capabilities. Thicker wetsuits provide more warmth, making them suitable for colder waters.
3. Neoprene Material Properties
Neoprene is a synthetic rubber known for its excellent thermal insulation properties. It has a unique structure that traps air bubbles, enhancing its insulating ability. Different wetsuit models come in various thicknesses, allowing you to choose the right suit based on the water temperature and your activity level. For example:
- 3mm Wetsuit: Ideal for warmer waters (approximately 60°F to 70°F).
- 4-5mm Wetsuit: Best for cooler waters (below 60°F).
- Shorty Wetsuit: Suitable for warmer conditions, providing coverage while allowing for mobility.

-
Performance Advantage: Due to its superior features, Yamamoto neoprene is often the choice of competitive swimmers and triathletes seeking the best performance in their wetsuits.
Does a Wetsuit Keep You Dry?
While the name “wetsuit” suggests that it keeps you dry, the reality is a bit different. Here’s a breakdown of what to expect:
1. Water Entry
Wetsuits are designed to allow a small amount of water to enter. This water is then warmed by your body heat, as previously discussed. However, if you’re looking for a suit that keeps you completely dry, a wetsuit may not be the best choice. Instead, consider a drysuit, which is designed to keep you completely dry by creating a waterproof seal.
2. Water Resistance
Wetsuits do provide some level of water resistance, mainly through their neoprene material and sealed seams. Higher-quality wetsuits often feature glued and blind-stitched seams that help minimize water entry. However, it’s important to remember that some water will always find its way in, especially if the suit is not fitted correctly or if there are any defects.
3. Comparing Wetsuits and Drysuits
- Wetsuits: Allow a small amount of water to enter, which is warmed by your body heat. They are best for activities in cooler water where insulation is a priority.
- Drysuits: Are fully sealed and designed to keep water out completely. They are ideal for extreme cold conditions but often come with a higher price tag and may require additional layers underneath for insulation.
Swimming Wetsuit: A Beginner’s Guide
Choosing the right wetsuit can be daunting, especially for beginners. Here’s a comprehensive guide to help you make an informed decision.
1. Understand Your Needs
Before shopping for a wetsuit, consider the following:
- Water Temperature: What will the average water temperature be during your activities? This will determine the thickness of the wetsuit you need.
- Activity Type: Are you participating in triathlons, surfing, or open water swimming? Different activities may require specific features in a wetsuit.
2. Choose the Right Thickness
As mentioned earlier, wetsuits come in various thicknesses. For beginners, here’s a general guideline based on water temperatures:
- Above 70°F (21°C): A 2mm shorty wetsuit or no wetsuit may be sufficient.
- 60°F - 70°F (15°C - 21°C): A 3mm wetsuit is usually ideal.
- 50°F - 60°F (10°C - 15°C): A 4mm or 5mm wetsuit will provide adequate insulation.
- Below 50°F (10°C): A thicker wetsuit (5mm or more) or a drysuit is recommended.
3. Fit and Comfort
A proper fit is crucial for a wetsuit’s performance. Here are some tips for finding the right size:
- Snug Fit: The wetsuit should fit snugly without being too tight. Check areas like the shoulders, chest, and legs for a comfortable yet snug fit.
- Check the Length: Make sure the suit isn’t too long or short, especially in the torso. The neck should also fit snugly to prevent water from entering.
- Mobility: Raise your arms and move around in the suit to ensure you have a full range of motion. Look for wetsuits with flexible panels in the shoulders for enhanced mobility.
4. Consider Additional Features
When selecting a wetsuit, look for these features that can enhance your experience:
- Seam Type: Look for glued and blind-stitched seams, which provide better insulation and minimize water entry compared to flatlock seams.
- Zipper Placement: Wetsuits can come with back zippers or front zippers. Choose the type that you find easier to put on and take off.
- Suits with Sleeves vs. Sleeveless: Long-sleeve wetsuits provide more warmth, while sleeveless designs offer more freedom of movement. Consider what’s best for your activity.
