Abstract
The Scandinavian cross-country ski dress covers only about two thirds of the body surface area (trunk, arms and thighs). The peripheral area (head, hands, legs, and feet) is covered by garments which are not an integral part of the dress. Selective cooling of the peripheral area in six subjects in a climatic chamber showed that a general feeling of being cold was achieved by lowering the skin temperature in the peripheral area. The same general thermal sensation was also arrived at by keeping the peripheral area warm and cooling the central skin area. 'I'he general thermal sensation was related to the average weighed skin temperature, irrespective of the location of the cold and warm surface areas. In the evaluation of thermal comfort of any clothing system, attention should be paid to the insulation of the parts of the body which are not covered by the garments under investigation.
