I LOVE this backpack! I strictly use this bag for travel as my personal item. It fits nicely under the seat, has tons of pockets for various items, and it's lightweight and portable. I went to San Diego a few months ago for a conference and purchased 5 books while there! I was able to get all 5 books, my shoes, wallet, toiletries, and other items into this backpack on the return trip. This weekend, I went to Tampa and only brought this bag - nothing else! I traveled with 3 dresses, a skirt, swimsuit, a pair of sandals, toiletries, and a book. All of it, fit into this backpack! I love the divider that separates the top from the bottom, which allows you to carry various items and keep them separated. I just started using the side pocket in the back of the bag for easy access to my wallet and phone. The zippered pocket at the top is helpful to easily stash and grab headphones, lotion, etc. while on the plane. And, since I use it for travel, I use the lunch pail for all of my toiletry and make up products. I finally feel like I have a great travel set up with my carry-on and this backpack. I get excited to travel just so that I can use this backpack!! Highly recommend it.
