Why we wear wetsuits and how they work

A wetsuit is the unsung hero of every kitesurfing adventure. It keeps you warm, protects your skin, and even makes you look a bit like a superhero (minus the cape). But have you ever wondered why we wear them and how they actually work? Let’s dive in.

Not every destination requires a wetsuit. Brazil, for example, is perfect for a bikini with a rash guard. But a session in Cape Town? That screams wetsuit essential. Before heading to a new kiting spot, check whether you’ll need one. If you’re unsure, bring it along—it’s better to be safe than ruin a session by freezing out.

Why do we wear wetsuits?

The simple answer: to stay warm and protected. But there’s more to it than that.

1. Temperature regulation: Wetsuits are designed to keep your body warm in cold water by trapping a thin layer of water between your skin and the suit. Your body heat warms this layer, providing insulation against the cold environment. This is vital for preventing hypothermia, especially in water temperatures below 21°C.

2. Skin protection: From the harsh sun to sharp reefs and jellyfish stings, a wetsuit acts like armour, shielding you from potential hazards. Plus, if you take a big crash, the neoprene offers a bit of padding. Let’s be honest: wiping out in a wetsuit is far less painful than in just a bathing suit.

3. Improved buoyancy: Neoprene, the primary material in wetsuits, provides buoyancy, making it easier to float and recover from crashes (and we all know how often that happens).

4. Enhanced performance: A snug wetsuit provides mild compression, improving blood circulation and muscle support. This helps reduce fatigue and allows you to kitesurf longer and more efficiently.

5. Peace of mind: Knowing you’re warm, protected, and equipped for the session lets you focus on kitesurfing without distraction. That psychological comfort can make all the difference in enjoying the water.

How do wetsuits work?

Wetsuits are made from neoprene, a rubbery material filled with tiny bubbles of nitrogen gas. This gas traps heat, making neoprene an excellent insulator. Here’s how it works:

1. Insulation through trapped water: When you hit the water, the wetsuit lets in a small amount of water. Your body warms this layer, creating a barrier that keeps you warm, even in cold conditions. 

2. Thickness matters: Wetsuits come in different thicknesses, usually measured in millimeters. For example, a 3/2 wetsuit (3mm on the torso, 2mm on the limbs) works for moderate temperatures, while thicker wetsuits (5mm or more) are better for winter sessions.

   • Trade-off: Thicker suits provide better insulation but restrict movement. It’s like the difference between a T-shirt and a hoodie—the hoodie is warmer but less flexible.

   • Pro Tip: If you tend to get cold, don’t skimp on thickness. A 5/3 wetsuit works well in most colder climates.

3. Seals and zippers: High-quality wetsuits have tight seals at the neck, wrists, and ankles to minimize water flushing (when cold water sneaks in). Features like taped seams and advanced stitching ensure a snug fit while maintaining flexibility.

What happens when you forget your wetsuit?

Two words: utter regret. Without a wetsuit, you’re exposed to the cold, which can drain your energy quickly and cut your session short. Plus, nothing kills the stoke like freezing spray smacking you while everyone else is shredding in cozy neoprene.

Choosing the right wetsuit

A wetsuit works best when it fits well. A poor fit can ruin its insulating properties or make it uncomfortable to wear. Here are some tips:

1. Fit is key: A wetsuit should feel snug but not suffocating. If water is sloshing around inside, it’s too big. Too small, and it’ll be a nightmare to put on and wear. Try one on in-store, and don’t worry if it feels tight initially—neoprene tends to loosen over time.

2. Consider sonditions: Warmer waters might only require a thinner wetsuit or a shorty, while colder climates call for thicker suits, possibly with hoods, gloves, and booties. If you don’t have the right thickness, check for rental options at your destination.

3. Flexibility and durability: Look for a wetsuit that balances both. Kitesurfing-specific wetsuits are often designed to handle harness wear and frequent crashes. While surf wetsuits can work, some may not be as durable under kiting conditions.

Final Thoughts

Your wetsuit isn’t just gear—it’s your ticket to kitesurfing in any condition. Whether you’re tackling icy waves or tropical breezes, this humble piece of neoprene has your back (literally).

Next time you’re packing for a session, double-check for your wetsuit. Trust me, you’ll thank yourself later. If it’s especially cold, don’t forget the hood, booties, and gloves. With the right gear, no conditions are too extreme for an epic kitesurfing session.

Never forget: your wetsuit is more than a necessity. It’s your partner in comfort, safety, and performance out on the water.
