I tried this pack on at REI and I loved it. I'd like to order it from backcountry but I noticed that the pack being sold here does not have the torso adjustment capability. I would have thought the packs would be pretty much identical. Is that correct? These packs can not be adjusted to torso size?? If so, bummer!
This IS the same pack you saw at REI and it IS torso adjustable in the sense the harness can be adjusted up to 4 in (10 cm) of variance in each torso size.
Perhaps you are thinking of the custom-moldable hipbelt? It has that too, and it is awesome!
According to Osprey, this pack has "three torso sizes for each style Ariel, these packs provide an unparalleled range of fit for women.".
The Kestral pack is another torso-adjustable pack Osprey makes.
The bottom line is if you buy a size according to this size chart, you will be happy with this pack. If you find yourself inbetween, go up a size.
