The smallest of the two pieces I haven't quite figured out, I don't know why anyone would try to sell such a thing.
The "larger" piece is quite small itself! I'm a 6'4", 230 lbs guy so I take into account that my clothes may take up more room but I started packing and could only get 3 pairs of pants and two t-shirts in it before I hit capacity.
I understand this is carry on but if it were any smaller I could use it as a shaving kit.
