Familiarity: I've put it through the wringer
I finally caved and got an X-mug and the X-bowl and they are so worth it. Anyone who backpacks knows that sometimes even small pieces can make your whole packing experience pretty tricky if they are awkward shapes (i.e. plastic mug and bowl.) It becomes obvious when you have to do it day after day. The flat collapsed shape just magically makes the puzzle pieces fit so much easier! Make packing easier, just get it.
