This is a nice long-distance/ultralight pack with one Achille's heel. The main packbag is a versatile, common design nowadays. The front pocket and big side pockets are nice for quick access to gear, and surprisingly carry quite a bit. The silnylon, while thin, seems like it will hold up well as long as you pay a little attention to it. The thicker fabric in higher-wear areas inspires more confidence. Overall it carries pretty well, though it has a tendency to slip down my back at the lumbar, and I would gladly trade a couple ounces for a full, more padded/structured hip belt. I've thru-hiked the PCT and AT, and nearly every other thru-hiker I've known gets rid of the top lid on their packs. Very sadly, Osprey doesn't give you that option with this pack, and the fixed lid drives me nuts. I'd much rather save those ounces (and have them in the hipbelt) and have quicker access to the drawstring into the main compartment. It's a shame because otherwise this pack would be perfect. FWIW, I like the color of it too, much preferred to the gaudy Exos series colors.
