Access the main compartment from the top or via the front zip pocket. Comfy AirCore suspension.

Big enough for an overnighter small enough for day trips the Osprey Stratos 40 Backpack is a do-it-all all-star of mid-size packs. The sophisticated AirCore suspension offers support that easily handles loads up to 30 lbs. and the hipbelt even does double duty providing small mesh pockets for handy storage of snacks sunscreen etc. Varied load configurations are a cinch thanks to side pockets compression straps and a floating top pocket. Jam a water bottle into a side pocket and then later in the day use the same side pocket and compression strap to carry your trekking poles. Meanwhile the floating top pocket extends to accommodate gear intensive endeavors. A zippered left front pocket allows for access to the main compartment often a faster method of reaching buried gear than digging down from the main top access.
