If you are given the choice of one thick blanket or 2 thin blanket what will you choose?

Wool is a poor conductor of heat .

Warm air trapped between the woollen fibres is not able to escape into the surroundings.

This prevents the flow of heat from our bodies out into the environment. 

Air would be trapped in the space between two thin blankets better than in a single thick 

blanket . 

Hence, we’d choose 2 thin blankets to cover during the winter.
