I'm pretty pissed off about this purchase. I got this one instead of the other KAVU type backpack because this one had a drink holder. Well guess what- the drink holder doesn't work for s***. Since getting it my water bottle has fallen out constantly, even just sitting the bag sideways, the bottle just falls right out. This morning my coffee travel mug popped right out, smashed open, and my coffee split everywhere. I am FURIOUS with this bag now, I feel like I got totally scammed.
