Having several lightweight layers of clothes is better then having one thick layer as air is able to get trapped surrounded by the many thin layers as well as inwardly the clothing itself.

The third and utmost layer is made up of a windproof jacket know as the shell of the clothing. These jackets have no additional insulation, ever have a cap and sometimes may be worn with over-trousers. An example of a windproof jacket commonly utilise in Antarctica is Gore- Tex.

It is most important to keep your extremities (toes, fingers) covered up as their surface area is greater than their volume and they therefore turn a loss heat easily.
