This spring Osprey’s award-winning “anti-gravity” (or AG) backpack harnessing system graduates from expedition-sized packs to the daypack, and nothing is lost in the transition. The lightweight frame, mesh back panel, stretchy shoulder harness and mesh hipbelt distributes the weight of pack evenly, providing unmatched dexterity while hiking. Dual compression straps help stabilize—and at 28 liters, you’ll use that feature unless you like to carry a lot of stuff. It also boasts a removable rain fly, zippered pockets at the hip, a direct-access hydration compartment, internal mesh organizational pockets, and a large zippered front panel. The three-dimensional construct of the harness makes it tricky to stash and forget it while on a plane, train or bus, but it’s ideal for intrepid hikers looking to haul some comforts into the backcountry.
