Now a satin comforter is not exactly theo sort of thing you'd tote off to a football game! It was made before the days of centra heating for use in the Canadian Maritimes, weather can be cold and damp.
Another, but more flexible idea is to get or make a plain cotton duvet cover, and sew patch or applique right onto the the top part of the envelope with no bat or other stuffing, then you can change back and forth between cool or warm duvets and have a 4 season system for one 'quilt'.
