What Our Gearhead(R) Experts Are Saying: "The Stratos 34 is my go-to for long hikes where I need room for extra layers and gear. The new AirSpeed suspension is unreal for airflow-my back stays cool even on steep climbs. It's easy to adjust, super stable, and the rain cover has saved me on more than one downpour." Built for big days and unpredictable weather, the Osprey Stratos 34L Backpack delivers the ventilation, organization, and carrying comfort needed to handle demanding terrain. Its AirSpeed(TM) suspension system combines an injection-molded frame with a tensioned mesh backpanel for a breathable, body-hugging fit that stays stable and cool mile after mile. The panel-loading design offers wide access to the main compartment, with thoughtful organization throughout-from dual hipbelt pockets for essentials to a lower compartment for extra gear or layers. The integrated rain cover and PFAS-free DWR treatment provide reliable protection when conditions turn, while durable recycled nylon construction keeps the pack light without compromising strength. Whether we're logging long day hikes, tackling summit pushes, or packing light for an overnighter, the Stratos 34L keeps us cool, comfortable, and organized for every mile.
