I love this bag. It's comfortable, looks nice (I bought green), has lots of pockets and is super light weight.Don't expect this pack to lug your kids schoolbooks, it won't hold up, but that's not really what it's marketed for. I bought this day pack as a secondary backpack to take out on day trips while on vacation and have since started using it on my daily hikes/bike rides. (about 1 month so far). I don't put a ton of stuff in it, but it was a huge upgrade from a drawstring bag I was using before.ProsIt is comfortable and light weight, which is great because it's hot outside. The chest strap was a nice bonus too. I never really used them before, but it definitely made long days hiking with the pack more comfortable.The zippers held up. This fact alone earns five stars. There are so many cheap bags with crappy zippers out there it's maddening. Again, don't expect to put a ton of weight in the bag - clearly not meant for that - but so far this bag has held up with regular use with light gear. The seams seem to be fine as well.Typically I put a 48oz metal water bottle, hat, wallet, keys, snacks, sunscreen and sometimes a laptop or umbrella in this bag. There's plenty of room to fit more, like a jacket of you wanted.ConsI do not like the side mesh pockets. It does not hold my thermos securely, but mine is supersized (48oz) so I don't know if a normal one would stay put. I feel like any thermos would just fall out if the pack isn't full. Theres not really any structure to the bag since it's a fold away bag, so I just throw it in the back or clip it to the top handle. It works fine that way, but beware if that's a deal breaker for you.There is also not any padding for electronics. Again, it's a foldaway bag, so I wouldn't expect any padding to be in there, but sometimes I wish there was when lugging a laptop, you'll need to put it in a soft case before putting it in the bag.Overall, I got it on sale for $25, which for me, is totally worth it. If you are looking for something lightweight and compact when you don't need it, this bag is a good choice. I've been using it daily for about a month & just had a look at the inside seams, etc and so far it's holding up. Again, I will say, don't overload it - that's clearly not what its meant for and I would expect it to rip or fail in some way, but for light weight items, it's good to go.
