Turning heads once again, the redesigned, lightweight Osprey Atmos 50 backpack now rests closer to the back while still providing unsurpassed ventilation.

  • Top-loading design features a floating lid pocket to allow extensive gear storage
  • Features twin front slash pockets with water-resistant welded zippers, stretch-woven front and side pockets and zippered mesh pockets on hipbelt
  • Innovative Stow-on-the-Go™trekking pole attachment allows you to stow and remove poles without removing pack
  • Osprey Airspeed suspension features an aluminum alloy frame and torsion rods for support and flexibility under heavy loads
  • Anchored in the lumbar area, the suspension system provides uniform pressure and comfort without annoying hot spots
  • Features gender-specific BioStretch™ fixed shoulder harness and hipbelt; perforated, waffle-pattern foam saves weight and enhances breathability
  • ErgoPull hipbelt closure relieves hipbone pressure by spreading the tension along both the top and the bottom of the belt, not in a single line along the middle
  • Hydration-compatible design with drinking tube portholes; reservoir (sold separately) fits in cavity behind mesh backpanel
  • Twin ice axe tool loops and bungee tie-offs let you lash on extra gear
  • Includes adjustable sternum strap and removable sleeping pad straps
