Osprey Sirrus 24 Backpack (2026)

The Osprey Sirrus 24 brings women's-specific comfort to ventilated day hiking, with a frame geometry tuned to fit and a suspended AirSpeed™ mesh backpanel that keeps cool air flowing on warm, sweaty climbs. Its 24-liter main compartment and six exterior pockets organize layers, snacks and trail essentials, while panel-zip access makes packing and finding gear effortless. The adjustable harness and softly padded, contoured hipbelt distribute the load for a stable, balanced carry mile after mile. Thoughtful touches reflect Osprey's trail pedigree: an integrated raincover shrugs off surprise weather, Stow-on-the-Go™ attachments stash trekking poles on the move and an internal sleeve keeps a hydration reservoir handy. Crafted from bluesign®-approved, 100% recycled nylon with a PFAS-free DWR, the Sirrus 24 delivers airflow, comfort and conscientious materials in one capable women's daypack.
