Why Performance Sailing Gear Truly Makes a Difference at Sea

While sailing, conditions are never stable, and what you wear does play a crucial role. Since 1979, SLAM has been developing technical sailing gear based on real needs; protection from the elements, comfort, freedom of movement, and, most importantly, reliability at sea. Fabrics, technologies, and design are crafted to perform even in harsh conditions.

Performance Sailing Gear: How It Changes the Way You Sail

The sea is inherently unpredictable. It demands careful preparation and clothing is no small detail. What you wear impacts everything; how you move, how long you stay focused.

 

A regular garment gets wet, cools the body, and restricts movement during maneuvers. A technical one, on the other hand, is designed to protect, manage moisture, and allow freedom of movement. This is the main difference.

 

Since 1979, SLAM has been developing performance sailing gear based on the real-world experience of sailors. Every choice, from fabrics to product design, is conceived to work in real conditions and onboard.

Discover the technical features of sailing gear. Which are they and why do they matter so much?

Why Technical Clothing Matters More in Sailing Than in Other Sports

Sailing takes place in an environment that combines multiple factors at once: 

  • water  
  • wind  
  • salt  
  • humidity  
  • sun  
  • temperature fluctuations  
  • quick movements  

 

Even during the same outing, conditions can change rapidly. Moreover, the body alternates between very dynamic moments and more static ones while onboard. During a maneuver, you quickly move between ropes, the helm, and adjustments. Shortly after, you may be exposed to splashes, wind, and sudden humidity.

 

This is why technical sailing gear must do multiple things simultaneously; protect, insulate, and follow body movements. And its effectiveness depends not only on the fabrics used but also on how the product itself is designed.

A Sailing Garment Perfoms When Multiple Features Work Together

When it comes to technical sailing gear, the synergy between multiple features is key—they must work together within the same system.

Waterproofness Sailing Gear: Staying Dry in Humid Conditions

Onboard, water is everywhere; waves, wind-driven spray, constant contact with wet surfaces, or rain. This is why waterproofness is one of the most important requirements for technical sailing gear. But it’s not enough just to 'keep water out.' If the garment becomes a sealed barrier, sweat will get trapped inside, creating discomfort. 

Breathability: Protection Outside, Moisture Management Inside

While sailing, you often move from calmer phases to physically intense moments. During racing maneuvers, the body generates a lot of heat. If sweat isn’t properly evacuated, the internal microclimate becomes unstable, leading to: 

  • a greater sensation of cold  
  • less comfort  
  • less focus  

 

Waterproofness and breathability should never be considered as separate technical features. In more advanced sailing gear, they always work together.

Stretch and Freedom of Movement: Your Gear Must Follow Your Body

Tacks, gybes, position changes, and rapid adjustments. Every movement onboard must remain fluid and precise. A rigid, heavy, or poorly designed garment restricts movement and causes fatigue over time. 

Ergonomic fit, stretch fabrics, and product design are always key, especially for faster classes. 

Thermal Protection: The Cold Feels Worse at Sea

Even when the temperature outside doesn’t feel particularly low, wind and humidity can make it feel much colder. Therefore, you need technical apparel that traps heat without becoming bulky and losing effectiveness in a humid environment.

Durability and Protection in Highly Exposed Areas

Knees, seat, friction points, and contact with equipment; onboard, wear and tear are a big problem. Good technical sailing gear must be durable and reliable even after intense and repeated use.

UV Protection

At sea, sun exposure is intensified by the reflection off the water’s surface. During longer outings or in warmer months, built-in UV protection in fabrics becomes not just practical, but essential.

So What Really Matters Onboard?

At sea, it's not enough to wear 'a good garment.' You need products specifically built to protect from water and wind, even when weather conditions change rapidly. Gear that manages humidity and allows freedom of movement without ever being an obstacle.

All of this, together. Because if even one of these elements fails, you’ll feel it immediately. You lose comfort, energy, and focus. 

SLAM Technologies to Meet the Concrete Needs of Sailors

SLAM Shield 20: Complete Protection from Water and Wind

SLAM Shield 20 is a proprietary technology developed to address one of the most important needs in technical sailing; staying protected from water and wind while maintaining good moisture management inside.

 

This technology is based on a three-layer membrane structure, fully taped seams, and mechanical stretch fabric. It's designed to combine protection and freedom of movement:

  • waterproofness: 20,000 mm  
  • breathability: 30,000 g/m²  

 

SLAM Shield 20 provides effective protection against heavy rain and wind, even when onboard activities demand continuous movement and effort.

ThermoPlume®: Lightweight Thermal Insulation Even in Humid Environments

When it’s cold, the problem isn't just retaining heat. You also need to avoid weighing the body down and losing effectiveness as humidity increases.

Primaloft ThermoPlume® is a 100% recycled synthetic insulation designed to offer thermal protection even in humid conditions. It's essential when seeking both warmth and lightness.

Grid Fleece: Warmth, Lightness and Layering 

The Grid Fleece fabric has a honeycomb structure that helps trap air between fibers and retain body heat without adding weight. This is especially important in winter, when technical layering is used to face cold weather.

OD Tech: Lightness, Quick Drying and UV Protection

The OD Tech fabric family is designed for those seeking technical comfort and protection both while sailing and ashore. 

This fabric is designed to dry quickly and offer prolonged UV protection with built-in UPF 50+.

Product Design: From Ergonomic Reinforcements to Abrasion-Resistant Inserts

The performance of technical sailing gear doesn’t just depend on membranes and fabrics; it also depends on how the product is conceived.  

A concrete example is the design of 1.5mm neoprene wetsuits, developed by SLAM in collaboration with Ruggero Tita and Caterina Banti, Olympic champions in the Nacra 17 class. Direct collaboration with athletes who wear the gear in real-world conditions helps improve details that might remain invisible in a lab. 

Training, regattas, wind, high speeds, repeated movements, and variable weather conditions all become part of the development process.

Why Performance Technical Sailing Gear Truly Makes a Difference

To sail at your best, you need to rely on the right gear. When waterproofness, breathability, thermal protection, durability and design work together, technical sailing gear is no longer just a support—it becomes an active part of your sailing experience

And when everything works as it should, you're not just sailing better—you're sailing with control. That’s where the way you experience the sea really changes.
