Osprey Exos 38 Pack Video

Osprey Exos-series packs have become standard among thru-hikers and ultralight enthusiasts. The supportive Exos 38 is no exception and is perfect for superlight backpacking and day hiking.


  • Updated materials and hardware create a lighter pack than the previous version; the lid, key straps and attachment points are all removable
  • Superlight Airspeed™ suspension features a 6065 aluminum frame and breathable 3D tensioned-mesh back panel with side ventilation
  • ExoForm™ shoulder straps include a stretch-mesh energy gel pocket and a 15mm adjustable slide sternum strap with a built-in whistle
  • ExoForm hipbelt features an ergonomic, forward-pull cinch closure that lets you get just the right fit; seamless layered mesh provides comfort and cushioning
  • Removable floating lid includes top and under-lid zippered pockets for stashing trail essentials within easy reach
  • FlapJacket™ lid deploys to provide main compartment protection from the elements and top-down compression to keep the pack load stable
  • Hydration-compatible design places the reservoir (sold separately) in a cavity behind the back panel for easy refilling
  • Ultralight, 7mm webbing compression straps on the sides take up extra volume with minimal added weight; route the straps over or under the side pockets
  • Sleeping-pad straps and a single tool attachment with bungee tie-off let you strap extra gear to the outside of the pack
  • Front and side stretch woven pockets provide handy spots for stuffing a rain jacket or water bottle; zippered hipbelt pockets give you a place to stash energy food
  • The Osprey Exos 48 Pack is made with 100-denier nylon and ripstop nylon for ultralight durability
