Does this model have pockets?

Asked by: Jimmy
The pockets are not on the hipbelt itself, they are on the pack. This hipbelt is only compatible with the new Osprey Aether or Ariel AG packs.

Is this hip belt same as the Aether AG 60? If not, where can i order the same hip belt? And does this hipbelt fit Aether AG 60?

Asked by: Agnes
This hipbelt is the same belt that comes stock with the Aether AG 60, 70 and 85 packs.

I have the Medium size Aether AG 70, and the fit is right but the hip belt is completely tightened down to feel comfortably supported-- how much extra tightening space would I get buying a small hip belt?

Asked by: Timothy
​The small belt will reduce the space by 3 inches.
