plussunderlag

Plussunderlag is a term originating from Scandinavian languages, roughly translating to "plus" or "additional" underlayer. It refers to a layer of clothing worn beneath the primary outer garments, specifically designed to provide extra insulation and warmth. This concept is often employed in cold-weather conditions or for activities that involve prolonged exposure to low temperatures.

The primary function of a plussunderlag is to trap body heat close to the skin, creating a microclimate that enhances comfort. These garments are typically made from materials that are effective at wicking moisture away from the body, preventing the wearer from becoming chilled by sweat. Common materials include wool, fleece, and synthetic fabrics like polyester.

The design of plussunderlag can vary, ranging from simple long johns and thermal tops to more specialized garments with specific features like thumbholes or flatlock seams for reduced chafing. They are usually designed to be close-fitting to maximize their insulating properties and to be worn comfortably under other clothing without adding excessive bulk. In essence, a plussunderlag is a functional component of layered clothing systems, crucial for maintaining thermal regulation in challenging environments.
