What Our Gearhead(R) Experts Are Saying: "The Stratos 36 is my do-it-all pack-big enough for overnights, compact enough for long day hikes. The AirSpeed suspension keeps air moving, even when it's loaded down, and the fit system adjusts perfectly to my frame. It's seriously comfortable, even on those 15-mile days." When our hikes turn into fast-paced overnights or gear-heavy summit pushes, the Osprey Stratos 36L Backpack keeps everything secure, ventilated, and easy to access. Designed with the new AirSpeed(TM) adjustable suspension system, it offers a breathable, supportive carry that feels light and balanced from trailhead to camp. The 36-liter capacity strikes the perfect balance between space and mobility, with multiple access points-top drawcord, side zip, and bottom compartment-to keep essentials organized and within reach. Thoughtful touches like dual hipbelt pockets, a trekking pole attachment, and a dedicated hydration sleeve ensure we're prepared for any trail condition, while the integrated rain cover keeps our gear protected when the weather turns. Made from durable, recycled bluesign(R)-approved nylon with PFAS-free DWR, the Stratos 36L blends responsible design with rugged performance for hikers who want comfort, convenience, and reliability in one streamlined pack.
