Great bag for every day use

I have the XS size and I love it. It fits my personal essentials, a bottle of water and a book. It's also light enough that it doesn't strain my shoulder. I can access my things easily by swinging it around vs using a backpack. I just wish it had a pocket on the back of the outside (for mail), a big open pocket on the inside and a handle on the top. The padded strap that came along with it kept sliding around so I took it off. It worked much better for me that way. It retains it's shape with a bottle or a book inside it unlike the bigger models.
