My humble, or not so humble opinion, is my Utilikilts blue denim original - now well worn and very soft.

In colder weather my Utilikilt brown leather, feels like a well broken in baseball glove (Same with my RKilt leather when I fit it).

And also my USA Kilts semi-traditionals are more comfy for me than the casual because I wear them without a belt...that gives my beer belly more comfort. My Freedom Kilt dress model would fit in there too.
