Our Reviews

  • A workhorse pack that gets the job done.

Reasons NOT to buy:

User Reviews

  • Not the lightest option on the market.
  • The front opening is a bit tedious to access.
  • No built-in rain cover.

Expert Reviews

  • No zippered side pockets for easy access.
  • Expensive when compared to other options.

Our Reviews

  • While this pack has Osprey’s “anti-gravity” system, it is not as effective as the version on their smaller packs like the Atmos.
  • This pack tends to squeak and make noise in weird places which can be annoying.
  • The sleeping pad straps are too short if you want to attach anything larger than a single foam pad in that spot.
  • While Osprey typically makes terrific packs, they managed to both over- and under-engineer this pack at the same time.


The Osprey Packs Aether AG 85L Backpack is a durable, heavy-duty, and comfortable pack that is well-suited for those who carry heavy loads and want a fully functional backpack. Despite being expensive when compared to other options, the numerous pockets, removable top-lid day pack, and efficient weight transfer make this a high-quality choice for those who want to carry heavy weight without sacrificing comfort and durability.
