Brown Sugar is a winner!
I spent lots of time researching lightweight women's specific packs and in my opinion Osprey has nailed it! The Aura is a perfect fit for my narrow shoulders and the hip belt fits my curves perfectly. At first I was skeptical of the thin mesh padding on the straps and hip belt, but after one use it turned out to be considerably more comfortable than my old heavily padded beast of a pack. I also love the curved mesh back panel which keeps my back cool and dry and has enough space to store a hydration bladder so I never have to worry about fishing it in and out of the main compartment. There are tons of handy features and compartments on this pack to keep all my stuff organized and easily accessible while on the trail.
I've used the pack on multiple trips in the Sierras, including a 7 day High Sierra Trail trip, and was easily able to carry everything I needed for the week, including a bulky bear canister. My only warning would be that this pack is not designed to comfortably handle 50-60 pounds of gear, so if you're still rockin' the 10 pound tent, this may not be the pack for you. Or better yet, buy the pack and get some new lightweight gear to go along with it!
Bottom line - I love this pack. Love it so much that I'm probably going to buy the Aura 35 for smaller weekend trips. Plus that brown sugar color is just so darn sexy.
