Fit doesn't match sizing chart - Osprey Aura AG 65 Backpack - Women's

Taking off a star because I ordered the pack according to the sizing chart provided, and it's a bit too short for my torso. Came back to try the larger size and they're all gone. I can't find this particular backpack anywhere else. So I either return it and start over with searching for the right pack or stick with one a bit too small.
