Osprey Atmos 50 AG Pack - Men's


See available overnight packs


Head out for a weekend, a week or an epic thru-hike: the Atmos AG 50 can handle whatever you want to throw in it. Osprey's brilliant Anti-Gravity suspension supports the load and holds it slightly away from your back for comfortable carrying through the kilometres. Tons of pockets let you organize all your gear so you're never left searching for a place to stash your trail mix, and side compression straps let you keep things streamlined as you eat through your food. On lightweight missions, swap out the top lid for the included FlapJacket lid to save weight.

  • Made of lightweight 100-denier nylon with durable 210-denier high-density nylon in high-wear areas
  • Anti-Gravity suspension with peripheral frame and suspended mesh back panel effectively transfers the load to the hipbelt while letting cool air flow through to your back
  • Die-cut foam shoulder straps have a structural load-lifter bar for weight transfer and comfort
  • Fit-on-the-Fly hipbelt can be easily adjusted on the go
  • Removable floating top lid can be replaced with the included FlapJacket lid to protect your gear and minimize weight
  • Stretch-mesh front and side pockets let you stash gear on the fly
  • Zippered hipbelt, front and lid pockets provide secure storage
  • Bottom zippered compartment provides a dedicated home for your sleeping bag and has a removable divider
  • Dual tool loops with bungee tie-offs carry ice axes
  • Stow-on-the-Go trekking pole attachments let you stash your poles without removing the pack
  • Side compression straps and removable sleeping pad straps cinch in the load and allow you to attach extra gear
  • Hydration sleeve holds a 3L reservoir (sold separately)
  • Osprey rates this pack as best for loads 25-40lbs/11-18kg
