First impression I got from this pack is that it's going to hold up to being a crag bag, which is what I got it for. It carries 30lbs well and close despite the ventilated back. I do wish the tensioned mesh was a little tighter, as it does collapse with a full load in the pack. The shoulder pads are plenty beefy enough, and I haven't had any shoulder or neck pain after lugging this around with 30lbs for a few miles. I also especially like that the sleeping bag compartment is self - contained while also being collapsible. So if your gorp or whatever busts open in your pack, or you get some sand in there from your flops, it won't shake down into your sleeping bag. Many bags just have a little flap here that you snap into place to keep the sleeping bag down, but this pack's is a whole enclosed compartment. Really thoughtful from Osprey, although I'm sure ounce-counters will hate it. The outer material is nice and thick, and seems that it will stand up to being smacked on rocks and dragged a bit at the base of a crag. Also big points for the stuff-it pocket on the outside also having a zipper pocket integrated into it.

Downsides are that the mesh water bottle pockets have two openings each, one on top like most standard pockets, and one facing the front, so you can grab it on the go. Useless to me as you can't put the bottle back in that way without putting the pack down, in which case why wouldn't you just use the top opening. Because of this extra opening, the mesh pockets won't hold much other loose stuff. Minor gripe though, and it won't affect my use, and I give credit to Osprey for trying it out. Also, the hip pockets are pretty small, and I would have preferred the hydration bladder pocket to be external, as it takes up some of the 50L capacity when inside the pack as it is.

Overall, this is a great pack that many might overlook, but it really perfectly fills the middle ground between the super light Talon 44 and the beefy Atmos 50. Highly recommended.

This pack is extremely comfortable. Hiked in the heat this past weekend and found ventilation on straps and back harness to be excellent. Excellent job of transferring load to hips. No problems with front of hip belt strap "biting" me.
Two reasons this pack was not rated 5. First: hip belt pockets are very small. Second: lighter materials and smaller straps could make this significantly lighter.
Overall: look forward to using this pack on my monthly excursions into the woods.
