Why It's CoolIn both modes, the Outlander is exceptionally clean and stable, thanks to Osprey's trademark burrito-wrap pack bag: Foam-stiffened sides envelop (and protect) any load, so there's no slop. » It's trek-ready, with a zip-away, fully adjustable harness (padded hipbelt and shoulder straps). Go ahead, haul 50 pounds. Bonus: straps to hold your sleeping pad on the bottom. » A small daypack that clips into the top of the pack bag is the best of its ilk: It detaches in seconds, is hydration-compatible, and has a full lightweight harness. Plus, it's much more stable than other detachable daypacks. » The main bag (4,300 cubic inches) is organized with side compartments and internal compression straps.Hmmm . . .It's such a fine duffel that I wish Osprey would include a shoulder strap.
