I own this product in the 22", 26", and 33" sizes and love it. It has a ton of room and though it doesn't fold into a small block (since it's a rolling product), it folds flat beautifully. I've used the 26" on three trips so far, the 22" on one, and I'm preparing for my first trip with the 33". Depending on what you need to do and how long you will be gone, I cannot suggest this family of products highly enough. Only thing to watch out for... It does NOT stand up well without your hand on the handle.
