Pretry good for the price.
TL;DR - If you're looking for just a casual bag that sees little wear or strain, this might be the bag for you. If you want something you can take to hell and back, look elsewhere.
I was looking for something a little more rugged. I'm a cyclist with a 10 mile commute to work every day. This bag has seen near daily use for about a year and it's starting to give up on me. The stitching that connects the magnet to one of the straps came apart and the magnet was lost ages ago. Definitely seeing some fraying/beginning rips on outer material. Wish the side bottle pockets were a little bigger. Also straps are def not real leather and seem kind of cheap. And maybe I'm being nitpicky but the drawstring closure often gets in the way and wraps around things as you pack. Might not seem like a big deal but with daily use this gets real annoying. Overall not a terrible bag at the price I got it ($45-ish if I remember correctly). And if you're using this as a school bag or light travel bag this will probably do the job. But considering my last bag was a $20 Jansport that lasted me damn near a decade I'm a little disappointed.
I will compliment it on two main things though. It is a lovely bag, and I received a lot of attention for how good it looked. Secondly, the waterproof aspect of it is phenomenal. When needed for waterproofing the drawstring comes in handy, and as a cyclist just trying to get home through a rainy night after work, this bag came through for me like that old Jansport never could.
But a year in and it's showing signs of giving up, and I'm starting the search for a new bag.
