Thermal Protection in Technical Sailing Gear: Managing Cold, Wind and Humidity

At sea, the cold is more intense. Wind and humidity accelerate the loss of body heat. 

If body temperature drops too quickly: 

• reactivity decreases 
• fatigue increases 
• overall performance worsens 
• comfort during sailing decreases 

Thermal protection depends on: 

• the insulating capacity of materials  
• humidity management  
• layering construction  

It’s not just about retaining heat, but preventing its loss. 

If the gear isn’t waterproof, water rapidly disperses heat. If it’s not breathable, internal moisture cools the body. That’s why thermal insulation, waterproofness and breathability must work together within an integrated system. Only then can the body maintain a stable temperature, even in variable conditions over time.
