For your body to retain heat it is proven that there are certain areas of your body which you must keep warm for the rest of you to feel warm.

First and most importantly is your head. Put on a hat.

Second is the area of your back between your shoulder blades and up the back of your neck. Wear a jacket.

Third is your mouth. Breathing in cold air that then needs to be warmed and then exhaling the warm air is just throwing away the heat. Wrap a scarf around your mouth and nose.

Fourth is the back of your hands. You can cut the fingers off gloves and still have your hands feel warm.

Last are the tops of your feet. Nice wool kilt hose help here.

Keep these areas covered and warm and the rest of you will feel warm.

Having bare legs does not cause as much heat lose as most people think, so kilt wearing is perfectly warm down to temps. that would be too cold even with trousers.

Wind chill is the danger while kilted. At temp. and wind combinations that lower the wind chill below 0 f or -32c you may feel warm but the exposed skin of the knees may frost bite.
