Sizing chart

Anti-Gravity Aether 70.

The Aether AG™ 70 has the pedigree few backpacks can match, with a design for long-distance thru-hikes, alpine backpacking and week-long adventures in the backcountry. Osprey equipped the Aether AG™ with a convertible top-lid DayLid™ daypack, creating a more versatile pack for long-haul carrying on multi-day excursions. The main pack has Osprey's Anti-Gravity™ Technology, which utilizes a continuous, suspended backpanel of lightweight mesh that extends from the upper torso through the lumbar area, wrapping the wearer in breathable comfort. It then combines Osprey’s adjustable IsoForm5 harness with the custom heat molding CM™ hipbelt, which deliver an outstanding fit and comfort for carrying heavy loads over long distances. Both the harness and hipbelt are interchangeable to provide users with the best possible fit.

  • Convertible top-lid DayLid™ daypack
  • LightWire™ tensioned, full peripheral
  • Anti-Gravity™ Technology
  • IsoForm5 harness & CM™ hipbelt
