The reson why wool keps us warm is due the air pockets between fibers of wool.

The air around us is a not a good conductor of heat. If we could keep the air around us still then it would act as a good insulator of heat. But this is not possible as air naturally moves around and the movement of air carries heat away from us by a process called convection.

But when we wrap our bodies in wool, we surround ourselves with a lot of tiny air pockets. The fibers of wool prevent th movement of air in the air pockets, keeping it still. This property of wool helps it keep us warm.
