KC - that is funny - I ordered the Aether 85 today. I bought an Osprey Atmos this past weekend but in the short torso version it wasn't much bigger than my other back pack. I guestimated I need ~ 5-700 cu inches over my present 3600. The 70 was right at 4100 cu in, the 85 in short comes in at 5000. With compression straps, I should be able to make it work for summer trips around home (1-3 nights) and elk trips for 2-3 nights with late fall/winter appropriate gear. I really liked Osprey packs.
