Boog
I haven't had any problems with it but I also haven't been caught in heavy rain. It's been fine in the occasional shower or two but I never trusted the rain cover anyway. It's like a tent that keeps you dry until you touch the inside of the wall and you're wet . My only real complaint is the main compartment could be expandable rather than the side pockets but I do like the strap loops that allow you to stack more bags on top. Other than that it's been a very durable bag.
