Why We Like The Osprey Eja Pro 55L Pack

Shaving almost a pound from its popular Eja series, Osprey designed the new Eja Pro 55L Pack with thru-hikers and ultra-light backpackers in mind. The face fabric blends Nanofly high-tenacity nylon with ultra-high-molecular-weight-polyethene for a lightweight but durable build that keeps weight to a minimum. For those of us who file down our toothbrushes for the trail, the floating lid can also be removed to shed another 74 grams/2.6oz of weight. Still, the Eja Pro doesn't sacrifice comfort in the name of weight savings. Osprey's ultralight Airspeed suspension system features four inches of adjustability in the torso for a dialed fit, a LightWire frame for stability and flex, a breathable mesh backpanel and mesh yoke to maximize breathability and back aeration, and an EVA foam-padded hipbelt with dynamic stretch for comfort. Osprey also spared several pockets in the scaled down Eja Pro, including external stretch pockets and accessible hip belt pockets, and provided us with plenty of external lash points and compression straps to secure items outside our pack while keeping everything cinched down compactly. This is the perfect pack for the ounce and gram counters among us—and the most comfortable pack in its weight class.
