Thermal insulation for gloves has also been measured to assess comfort using thermal hands. However, the previous studies mainly focused on the thermal insulation among different types of gloves, rather than across different-sized gloves of the same type. Actually, the air gap thickness and volume between the skin of the hand and the gloves varies with the size of the gloves and on different locations on the hand, thereby affecting the heat and mass transfer between the skin and its thermal environment.

Consequently, different-sized gloves will affect the thermal responses of hand and fingers as well as the thermal comfort. To design the next generation of highperformance gloves, it is critical to investigate the effects of size/fit on thermal insulation of gloves to enable both thermal protection and thermal comfort. In this study, the thermal insulation of two types of gloves with different sizes was measured and the effect of size/fit on thermal insulation was established.
