I've had this bag for a month or so. It looks great, and is very comfortable. The best part is the zipper, which is large and satisfying to close and open. The outside feels like it's well-made, and the green body color with beige and gold (straps) highlights is very cute.I'm a student - so I use the bag for class and lots of little stuff too. Generally, in the main pocket, I carry 5 notebooks and a ton of pens; my 15.6" laptop which fits comfortably in the laptop pocket; gym clothes (whole outfit) and a towel; and if the stuff I put into it isn't too big or heavy, a lunchbox. It's a large compartment. If I didn't include the lunchbox, I would still have like 1/4th of ths area open for other stuff.Like others have said, the pockets on the outside are big too. I keep my earbuds, phone, and my wallet on one side and there's still room for other stuff. On the other side, I just have a random assortment of items like lip balm or lose change. It could easily fit a water bottle or umbrella like advertised, but I haven't needed to use it for either yet.I've only used it in a rainstorm once, and it wasn't particularly heavy - but all my stuff stayed dry.The only complaint, and this is something easily remedied if you care more than I do. The straps easily get loose if you move them the wrong way. It's a little annoying, but nothing damning.Great bag.
