For committing thru-hikes where every gram counts, the Osprey Eja Pro 55 pack provides a comfortable carry with its anatomic women's fit and AirSpeed™ suspension system that adjusts to your body.


  • This pack is nearly a pound lighter than the Eja 58 and features a more fine-tuned adjustment system, making it one of the most comfortable thru-hike packs in its weight class
  • Features a fine-tuned adjustment system for its ventilated AirSpeed suspension system with an anatomic women's fit
  • Tensioned mesh back panel keeps the weight off your back, enabling highly ventilated carrying comfort
  • Compression straps and a removable lid allow for functional capacity adjustment
  • Lightweight fabrics deliver durable performance
  • Sheds 2.6 oz. when the top lid is removed; integrated FlapJacket secures the main compartment opening, providing weather protection and load stability when the lid isn't used
  • Deep, dual access stretch-mesh side pockets
  • Dual ice axe loops with handle capture by the upper compression straps
