These bags are amazing. Family had one each on a trip around California. Each case has two separate compartments and so each is really like two separate cases, so you can split the contents, for example for first and second week. There is also a small zipped pocket, handy for holding overnight items and avoiding having to open the main case when just on a quick overnight stop. We also found the shape much easier to stack in the boot (we had to get three large and one medium in the back of the car!). Not sure how durable as one does have a small split in the side now, but these made our trip so much easier, I can live with it.
