Love this pack. Have already recommended it to several of my friends. I would highly recommend going into an osprey retailer and getting sized. I was a medium size but needed a small waste belt, which was easily swapped out. If you get the pack, definitely get the osprey reservoir; I have three camel backs and it blows them out of the water. Get the 3 liter considering it's an 85L pack. Pack spacing is for advanced backpackers; if your frustrated with it, use it a couple times and you'll learn to love it! Also, the top of the pack comes off and becomes a sort of fanny pack/day pack. At first I thought it was useless extra weight, however after using it several times I have found it to be a great way to explore the area around the campsite. Hope you enjoy the pack!!
