Base layer
Functional underwear acts as a base layer, supporting moisture management and helping maintain a balanced body climate during activity.
Functional underwear as the base layer
Functional underwear is the first layer in sailing and outdoor clothing systems and is worn directly on the skin. It plays a key role in layering by transporting moisture away from the body and creating the foundation for overall comfort. Combined with midlayers and outer shells, it forms an effective system for varying conditions.
Moisture management and breathability
Unlike conventional cotton underwear, functional base layers are designed to absorb sweat and move it away from the body. This reduces a damp feeling on the skin and supports temperature regulation. Breathable materials help maintain a stable body climate during physical activity.
Fit and comfort
A close fit is essential for base layer performance. Elastic materials adapt to the body and allow full freedom of movement. Seamless or low-seam constructions can further improve comfort and reduce friction.
Applications and materials
Functional underwear is suitable for activities such as sailing, skiing, or hiking. Polyester blends are commonly used, combining insulation with quick-drying properties. This ensures consistent performance in changing conditions.
