I bought this for day hiking about 15-20 years ago. The Aircore suspension worked well for keeping me cool. There are some minor scuff marks. The front stretch pocket has a small hole (about 1/8"), stable with use, and second superficially roughed up area (also 1/8"), but it's still sturdy and otherwise intact. The side stretch pockets are slightly stretched out but still usable. There internal fabric shows slight wear. The rest of the bag is in good shape and could clock many more miles! I've stopped using this because I have switched to a smaller hiking day pack, also Osprey brand, which stands by the "All Mighty Guarantee".
