Woolen clothes keep the body warm becauseWool is a poor conductor of heat because it traps a large amount of air between its fibres. The wool itself is not the insulator, the air is. This explains why, if your hands or feet are very cold, is is better to wear two thinner pairs of gloves/socks than one thick pair because the layer of air trapped between the two gloves/socks on each hand/foot acts as an extra insulator keeping the heat generated by the body inside the gloves/socks instead of letting it out. In the first instance wool is used by its natural wearer, a sheep, to keep warm on the exposed hillsides where it lives.
