Osprey Sirrus 36 Backpack

The Osprey Sirrus 36 women's hiking backpack transforms day hikes and overnight adventures with its game-changing AirSpeed suspension system, delivering cloudlike comfort through a mesh trampoline backpanel that keeps your back cool and dry even when the trail gets tough. Specifically designed for women with an adjustable fit system and padded harness, this 36-liter pack handles everything from sunrise summit pushes to weekend backpacking trips with impressive organization – featuring dual compartments with zippered bottom access so you can grab your rain layer without dumping your entire pack on the trail. The integrated raincover tucks away in its own pocket until you need it, while the hydration system compatibility and stow-on-the-go trekking pole attachment keep you moving efficiently whether you're chasing views or chasing daylight back to the trailhead.
