Osprey's research and development branch must have been working overtime to produce a pack like this one. Completely stocked with features you won't find on any other pack by any other company, the Aura is a hallmark of the Osprey line. The top-load storage compartment accounts for most of the Aura's 50 liters, but it also comes with a plethora of pockets and compartments to help you organize your gear. The welded, stretch woven front pocket found on this pack uses the most advanced technology available to provide an amazingly versatile storage solution. Effectively adding volume and storage capacity to the Aura, it will hold anything from a bike, board or boating helmet to a small down sleeping bag or spare clothes while remaining compact when not in use. The InsideOut™ compression straps on the side of this pack were designed to seamlessly move inside or outside the pack to secure gear either internally or externally while the Stow-on-the-Go™ trekking pole straps were designed to effectively store your trekking poles while you're on the move. The Osprey Aura 50 Backpack Womens is a great example of how Osprey came to be one of the leaders of the outdoor industry. Technical innovation, attention to detail, and a focus on comfort have led them to produce some of the best packs on the planet.
