This redesigned ultralight gear-carrier adds even more comfort and support with a highly ventilated foam suspension system and lighter materials for added weight savings and speed on the trail.


  • Ultralight and supportive, this pack offers the best of both worlds; its airy suspension is both light and comfortable for superlight backpacking and thru-hiking
  • Ventilated and supportive shoulder harness is made with slotted, mesh-covered foam; it features an adjustable sternum strap, built-in whistle and a pocket for energy gel
  • Mesh-covered, slotted-foam hipbelt tightens with an ergonomic, forward-pull cinch closure
  • Breathable, tensioned-mesh back panel pushes air to the sides for ventilation
  • 6061-T6 aluminum peripheral hoop frame effectively shifts load weight to the lumbar pad and hipbelt
  • Removable lid and over-the-top compression straps secure the main compartment; integrated FlapJacket™ deploys to offer weather protection when you're going lidless
  • Hydration-compatible design places the reservoir (sold separately) in a cavity behind the back panel for easy refilling
  • Ultralight compression straps on the sides take up extra volume without adding too much weight
  • Front and side stretch woven pockets, zippered mesh hipbelt pockets and an under-lid pocket make it easy to organize and access often-used items and snacks
  • The Osprey Exos 58 Pack features removable sleeping-pad straps; tool attachment features cord tie-offs that let you strap an ice axe or other tool to the outside of the pack
