Osprey's Aura AG 50 Women's Backpack checks all the boxes. It fits perfectly, works well, and has just the right amount of gizmos and gadgets to keep you organized and happy without being confused or overwhelmed. It all starts with Osprey's Anti Gravy Suspension, which uses a seamless panel of lightweight mesh that extends from the top of the back panel all the way to the hip belt, providing superior ventilation and a fit that's naturally contoured to your back. The upshot is effortless comfort and ventilation, so you can cover ground on multi day trips without stressing about your pack. The comfort of the Aura is boosted by the Fit on the Fly hip belt, which allows seamless adjustment of the padded portion not just the buckle straps so it rides comfortably on all sorts of hips. Internal and external compression straps keep your load from bouncing around, and the removable lid pocket lets you size down if you're looking to travel light and quick. Osprey integrated a special sleeping bag compartment on the bottom of the Aura, included an internal reservoir sleeve, and finished the package off with a compressive FlapJacket back pocket that cinches your load down further and lets you tuck a layer away for easy access. We'd also be remiss not to mention the top and front panel access points, which let you quickly and easily find gear no matter how deeply it's stashed away.
