We love the Exos for thru-hiking, but the Osprey Exos Pro 55 backpack is next level, shaving almost an entire pound of pack weight! Despite weighing just 3 pounds, it's still packed with features and comfortably carries up to 35 pounds.


  • Ultra-lightweight design keeps weight to a minimum without sacrificing performance: The pack's Ultralight AirSpeed suspension system consists of a 3.5mm powder-coated LightWire frame, a tensioned mesh backpanel, and foam-padded shoulder straps. High-tenacity NanoFly ripstop fabric has an amazing strength-to-weight ratio.
  • Built-in torso adjustability: An easy-to-access injection-molded "ladder" allows you to adjust the torso length of the pack for a customizable fit. The pack also comes in two sizes to accommodate different torsos. The Small/Medium best fits 17"-20" torso lengths and the Large/Xlarge best fits from 19"-23".
  • Modular design provides volume flexibility: Built-in compression and a removable lid allow you to adjust storage capacity and pack weight to suit the specific needs of any given adventure. Removing the lid reduces storage capacity by 9 liters and shaves another 2.6 ounces and an integrated minimalist FlapJacket cover still protects interior contents.
  • Sustainable construction that doesn't compromise on functionality or durability: Tested to ensure that they meet Osprey's demanding technical requirements, the fabrics used on the pack are bluesign-approved and the protective durable water-repellent treatment is PFAS-free.

  • Removable, floating single compartment top lid with key clip

  • Internal hydration sleeve with center back hose port and Osprey Hydraclip for easier reservoir hanging (hydration system sold separately)

  • Multiple front panel lash points for securing extra gear
  • Lower side compression straps designed to capture sleeping pad on front panel
  • Deep, dual access stretch mesh side pockets
  • Dual ice axe loops with handle capture by upper compression straps
