Baselaget

Baselaget refers to the concept of a "base layer" in clothing, particularly in outdoor and athletic contexts. It is the innermost garment worn next to the skin, designed to manage moisture and regulate body temperature. The primary function of a baselaget is to wick sweat away from the body to the outer layers, keeping the wearer dry and comfortable. This is crucial for preventing heat loss through evaporation, especially during physical activity in cold conditions.

Materials commonly used for baselaget include synthetic fabrics like polyester and polypropylene, as well as natural fibers such as merino wool. Synthetic materials are often favored for their rapid drying capabilities and durability, while merino wool is known for its softness, odor resistance, and excellent insulation properties, even when damp. Cotton is generally avoided for baselaget as it absorbs moisture and dries slowly, which can lead to a chilling effect.

The fit of a baselaget is typically snug, allowing for maximum contact with the skin to facilitate effective moisture transfer. It can come in various forms, including long underwear tops and bottoms, t-shirts, and sports bras. The choice of baselaget depends on factors such as the intended activity, ambient temperature, and personal preference. It forms the foundational layer of a multi-layer clothing system, working in conjunction with mid-layers for insulation and outer layers for protection against the elements.
