Four stars
-- I've been waiting a while to write this review. I mostly used this for my summer job. The main reason why I purchased this was because I needed an affordable bag to fit underneath the seat on the airplane for an upcoming vacation, had a trolley strap, and could also be used for regular activities. I recently got back from the vacation and this was a great option for a personal item/underseat bag. It's also really stylish and trendy-looking. There are many colors to choose from. Even if you don't travel often, this is a great bag to use everyday for work, school, the gym, etc. -- In the main compartment, it fit: a 32oz Nalgene water bottle (empty), a huge book that I had no business bringing, two toiletry bags (one for liquids, one for solids) roughly a quart-sized each, a small tech bag (about the size of two hands), an iPad mini, and a standard package of Huggies wipes. -- In the smaller zippered compartment, I had: a travel-sized pack of disinfectant wipes, a mini bottle of chewing gum, two lip balms, hand sanitizer, airpods, and earpods. -- The smallest zippered compartment is where I had my passport, wallet, and money case. While I would have preferred a zippered area inside one of these compartments (for extra protection of important items), the zipper teeth on this compartment have that flap covering iy, which can provide extra security, so it was okay (but this is clearly a backpack that can be used for travel, since it has a trolley strap to attach to suitcase, so it definitely should have had a secret zippered area inside the main or smaller compartment). -- In the side pouches, I just had a portable handheld fan on one side (which I bought from Target and highly recommened; it's the JisuLife brand) and a water bottle on the other side. -- Critiques: I will say, if you stuff this backpack, it'll be a bit difficult to slide the backpack on and off the handle of your suitcase. So that, in addition to the lack of a secret zippered area, is why I am giving it four stars instead of five. It's not a big deal and it didn't make or break my trip. It was just a minor inconvenience. -- Final thoughts: Like I said, I just needed something affordable. I'm not really a backpack person, but this did its job while I wait for the holidays to roll around and buy a discounted Away everywhere bag.
