Stratos 40 Backpack - 2200-2600cu in

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.
