Weather in my area of Texas can swing from a high of 82(degrees) one day and 2 days later a high in the low 30's with a high humidity and wind that can cut through a parka. I have several kilts which are in the heavy range but I find that the midweights are as comfortable as a heavy weight in this type of weather. I still haven't found anything to help with the wind but on calm cold days it seems the heat just 'stays up there'. You can see by the picture that I went out walking the 'terrors' in a snow storm and still had fun with them and this WAS a 'natural' day also. I know, I was probably crazy but what the hell. It was me, the dogs and a great snow storm. My wife decided I was crazy and went back inside after taking the picture.
