This bag is a nice size- it holds a lot, but it's not bulky. I bought this for hiking and gym use. I wish there were pockets on the outside for things like a phone, keys, chapstick. There's an inside zippered pocket that works for this purpose, but when I'm hiking I like to have easy access to my chapstick! When using at the gym, I can fit my shoes, water botttle and a sweatshirt. Nice!

The problem with this bag (which is a big problem) was that one of the straps broke immediately. I took it to the gym once, and when I was putting it on to leave I noticed that one of the straps had come completely detached. I don't know if it was just a defective product or if it was damaged by the original sellers (ShoeMall). The seller is replacing it...I think? But from now on I'll stick to Amazon.
