I will arrange to put on my winter tires this week, but I'm still in kilt. My Burnetts and Struth traditional kilt as has been said, is quite warm in winter, yet breezy in summer. Unless I'm going to be outside in the snow for extended periods of time, nothing more than wool hose are required to keep everything toasty warm. Keep your core area warm, but you lose most of your body heat out through your head, so put a cap on the chimney.
