Layering Guide
Layering is the foundation of staying warm, dry, and comfortable on the water. Understanding how each layer works will help you adapt to changing conditions and get the most out of your kit.
Use this guide to build your layering system, then explore our What to Wear guide for activity-specific recommendations.
Why Layering Matters on the Water?
Layering your kit properly is the easiest way to stay warm, dry, and comfortable in changing conditions. Whether you're out for a quick training session or a full-day sail, layering the right way can make or break your experience on the water.
The Basics
How It Comes Together
Your base layer sits directly against your skin and plays a key role in regulating comfort and temperature. There are two main types, and the right choice depends on your conditions and activity level:
Rash Layers (Nylon / Spandex)
Lightweight and close-fitting, rash layers are designed to keep you cool and protected. They become wet during use, creating a cooling effect against the skin while also offering UV and abrasion protection. Best suited to warm conditions and high-activity sailing.
Thermal Layers (Hot and Polypro)
Designed to retain heat, thermal base layers help keep your core warm in colder conditions. They work by trapping warmth close to the body and are ideal when layered under neoprene or outer layers. We offer 2 types of thermal base layers through out ‘Hot’ and ‘Polypro’ ranges. Find out more about the difference here.
Choose rash layers for cooling and UV protection, and thermal layers for warmth and insulation.

The mid layer is your primary source of insulation. It works by trapping heat and reducing heat loss — especially important when exposed to cold water and wind.
For watersports, neoprene is the most effective insulating material because it continues to perform even when wet.
Thermaflex (1.5mm Neoprene)
Lightweight and flexible, designed for active use where freedom of movement is key. Ideal for milder conditions or high-energy sailing where you generate body heat.
Supertherm (4mm Neoprene)
Thicker and more insulating, built for colder conditions and prolonged exposure. Provides maximum warmth by trapping more heat, making it ideal for winter sailing or colder waters. Find out more about the benefits of supertherm and the differences in our neoprene on our blog here.
Neoprene works by trapping a thin layer of water between the material and your skin, which your body then warms — creating an insulating barrier against the cold. The thicker the neoprene, the greater the insulation — but with slightly reduced flexibility.

Your outer layer is your shield against the elements. Its primary role is to block wind and water, helping to retain the warmth built up by your base and mid layers.
Lightweight Windproof Layers (2.5L and Airflex)
Designed for active use and changing conditions, these offer protection from wind and spray while remaining breathable and easy to move in. Ideal for high-energy sailing and milder conditions.
Midweight Performance Layers (SB1 Smock / Jacket)
A versatile outer layer offering a balance of protection and comfort. Suitable for a wide range of conditions, providing reliable defence against wind and water without adding bulk.
Insulating Outer Layers (Aquafleece)
The warmest outer layer option. Combines water resistance with insulation to reduce wind chill and retain heat, making it ideal for colder conditions and lower activity levels.
The more exposure to wind and water, the more protection you’ll need from your outer layer.

How to Choose the Right Layers for You
Your ideal layering system depends on your activity, the conditions, and how likely you are to get wet. Start here, then explore our What to Wear guide for detailed recommendations by sport and weather.
What's the difference between the 4mm Supertherm and the 1.5mm Thermaflex Wetsuits?
Our Supertherm wetsuits are made from 4mm neoprene with GBS (Glued Blind Stitching) and a superthermak wicking lining, making them ideal for colder conditions where minimal water ingress through the seams is expected. In contrast, our Thermaflex wetsuits are made from 1.5mm neoprene with flatlock stitching, offering greater breathability and flexibility, making them better suited for warmer waters.
Can I just wear a hoodie if it's chilly?
No! Cotton absorbs moisture and makes you colder. Stick to moisture-wicking layers.
What's the best fabric for a base layer?
For cold and wet conditions, Polypro is the ideal fabric to wear under your neoprene layers. Its naturally hydrophobic properties help wick moisture away from your skin, working together with the neoprene to keep you warmer and more comfortable
