This bag is great for what it was designed for! I dont understand the negative reviews. This is an add-on bag that attaches to a main backpack. It carries a hydration bladder perfectly. Those are not water bottle holders on the outside - they are meant to stash small items you need access throughout the day - like snacks or a bandana. It's lightweight and rugged. I've used mine a lot for over 2 years and it still looks like new. I wear it daily during summer as a daypack (I'm a summer camp director) and 2-3 weekends a month it goes camping with me (Boy Scout and Girl Scout camping trips - about half of those it's used as the added on bag it was made to be). I love the small pocket on front because small stuff like knife, lighter, and headlamp don't get lost amid other things and can be retrieved quickly.
