I use this product for rock climbing and guiding. I can pack a rope, full rack, water, food, guide book, extra clothes and all my equipment easily. My last pack had one top lid for everything and this pack has two lid compartments as well as the two waist pockets that allow me to organize all my "small" stuff so much more easily. I love the side zip compartments that allow me to get into my pack without having to pull everything out. I keep the first aid kit in the bottom compartment when guiding so that I can get to it quick and easy when needed; it is not in the bottom of my pack and hard to get to. The fit of the osprey pack for women is beyond compare. I have had packs from many different brands and this one fits like a glove. It was easy to adjust and find the right setting for my torso.
