In reply to nrhardy:
are you sure you would never want to use it as a climbing sac too? Not sure with either of those that you'd want the belt pockets if so and I think the Talon is maybe a little lightweight fabric wise for rubbing against rocks more than once in a blue moon. I think it is the same material as my Exos 58.
I'm not that sure that you would need to spend quite that much for a pack of that size unless you were going to climb with it, subject it to loads of abrasion, or run with it. You aren't going to be carrying so much in it that the back system will matter at all I guess.
22l is maybe a little small for even a one night wild camp unless you are going to pack your sleeping bag in a compression sack. Adding the weight of that you might as well start looking at something like the slightly larger Exos 38 . The lid detaches on the 38 for an even smaller pack it might be worth a look and a think whether it would be more versatile for you for a little more money and the same ball park weight.
