If you speak the language of Type II fun—alpine climbs with remote basecamps, or ambitious thru-hikes where the only trail is the one you make—the Osprey Aether Pro 70 pack is for you.


  • Streamlined design for those who appreciate efficiency and create their own specific systems for organization based on their unique needs
  • Dual front compression straps maintain a slim profile and stabilize loads; dual side compression straps provide additional load stabilization or can be removed to save weight
  • Large, dual removable hipbelt pockets—1 zippered and 1 with a cinch closure—keep a water bottle, snacks and smaller items close at hand
  • Removable floating top lid with zippered pocket for storing smaller items; Integrated FlapJacket™ protects contents from foul weather and rain during lidless use
  • Stow-on-the-Go™ trekking pole attachment allows you to stow your poles in steep terrain or whenever you need your hands free
  • Internal reservoir sleeve accommodates up to a 3L reservoir (sold separately)
  • Removable sleeping pad straps
