Yea, I love my Osprey Luna, I took it on my trip to the Grand Tetons, and it was great. It was comfortable and spread the weight evenly. I am a little guy, and the Crescent doesnt come in a small, so I opted to get the Luna, and I couldnt be happier. The only difference that I can tell is the color, which I got the green, or "jade", but other than that, they are pretty much identical to the Crescent, just smaller. The pack performed well, and had a great capacity, not only in the main compartment, but it was easy to strap things on to the packs outside. I love it.
