These worked great for our Scotland/England trip. I could pack much more than I could if I just folded my clothes and put them in my suitcase. The only thing I didn’t like is that I had to unzip and re-zip every time I wanted something. Do not overfill or the zipper will get stuck. These are more durable than I thought they would be. I didn’t use the large because I took my carry on and it would have taken up one whole part of my suitcase. It would be great in a bigger suitcase.
