I've been able to fold a StillWater into thirds instead of rolling it. That allows the kilt to be folded in half from top to bottom, and fit into a shorter bag. It might wrinkle a couple of pleats on the sides, but does all right otherwise. It also helps to put a rolled up shirt or cloth of some sort on the inside of the fold when you fold it from top to bottom. This keeps a wider curve at the fold. Sorry to have to say "fold" so many times. Hope this helps, and enjoy your trip.
