I needed a maximum-capacity "personal item" bag for travelling on long haul flights. I am so happy with this bag! It is well-constructed, and has plenty of pockets for stowing various things. It has a pouch for a water bottle on the side. The zipper is very sturdy...I packed that thing super full and it held! Strap is pretty comfy on shoulder, even when heavy. The material is water resistant...and I love the print, too! Functionality is most important, but when a bag is cute, too? WIN! It also has a loop for sliding over a suitcase handle, so you can stack it on top and roll...a nice feature, but be careful not to mistake the open loop for a pocket! I did...and had to backtrack in the airport to find what I had lost! But that's my goof...highly recommended!
