Abstract
Conditioned clothing for alleviating the effects of heat and cold has found use mainly in military applications. There are a few circumstances in industry where the provision of such clothing could be an economic proposition. Very often, however, there are other factors that militate against its adoption, e.g. the need for protection against hazards other than heat and cold, problems of wearer acceptance and interference with the work. Clearly the solution of these problems requires close co-operation between industry and clothing manufacturers as has been achieved in the nuclear industry.
