Woolen clothes :

1. Woolen clothing is thin with little air space between the layers.
2. We are kept warm by the air pockets that exist between the layers of cloth.
3. Wool is a poor conductor of heat, and the air pockets in the materials prevent air from passing through and into our bodies.
4. We can stay warm since there is less air flow and less heat transfer through the woolen fabric.
