I used this backpack as a challenge for my spring break trip this year. It really makes you think what is most important to take since you are the one carrying it around! I found it to be an awesome backpack and give it 4 stars only because the 'lid' was too flimsy, like opening the bag and wanting to lean the lid against the wall. It would keep falling.
Other than that, it got the job done. The zippers are top-notch!
