Cotton And Wool
Cotton traps heat by creating pockets of air between its fibers, which serves as insulation that retains body heat. When these air pockets are warmed by body heat, the cotton material then traps and holds that warmth close to the body. This is why cotton clothing can help keep you warm in cold temperatures.

You would want a thinner cotton fabric as it will allow heat to escape and keep you cool. You would want to stay away from any synthetic fibers like polar fleece in the summer as that kind of fabric tends to lock heat in.
