I have a couple buddys who wear Utili-kilts for hikes and some adventure oriented races/events. They are $$$$$$. I like them but prefer to put items in a pack rather than pockets so haven't done it. The one thing I do like is that its easier to add/remove running tights (for heat retention and skin protection).

Last year on a ultralight hiking website, I saw a pattern for making hiking kilt based on the puffy jacket/down quilt concept for extra warmth for morning/evening/campsite wear on trail.
