I got this bag for taking to the gym and on day hikes etc. It is roomy, sturdy, and comfortable, with lots of useful compartments.
I do however have one large gripe about it: the water bottle holders are next to useless. They are too tight, and cut too low on one side, with the result that if you have a typical 500ml bottle in them it might fall out of its own accord when you are walking. They bottles always fall out when you take the bag off, unless you take them out whilst the bag is still on your back. I find this rather irritating, and it the one thing that will put me off buying another bag of this type as a replacement.
