Woolen cloths are worn in winter but not in summer. Why?

Explanation

The fiber of woolen clothes enclose a large number of air cavities in them. Since both air and wool being bad conductor of heat prevent the loss of heat prevent the loss of heat by conduction from our body to surrounding. So we feel warm in winter in woolen cloths.
In summer , the temperature of surrounding is higher than the temperature of our body. if we wear the woolen clothes. then the heat from surrounding reaches to body through radiation but not through conduction. But heat can not flow from our body to surrounding due to conduction. As a result of it, our body temperature becomes more than normal and we feel discomfort.
