These bags are great. I had used them for short trips and they worked well for keeping everything organized. We just went on a 7 day Alaskan cruise and the bags made packing so much easier. I did order an extra large one for some shirts and jackets. The small ones held 7 pair of socks in one and 7 pair of underwear in the other. I neatly folded some starched shirts and other long sleeve shirts in one of the bags. They stayed very nice with no wrinkles. I used one for some pants, light jackets, etc.
Once we were onboard it was nice to be able to keep the items in the bags and place them in the drawers.
I would not travel again without them.
