Spent weeks and weeks searching for the right packs we could use on our 4 week backpacking trip to Thailand, but also use for day and overnight camping hikes. We tried on dozens of packs and settled on the Sirrus/Stratos 50s for him&her. The harness is the most comfortable harness on any of the packs we tried (and we tried on dozens). This was the biggest selling point - well ventilated to keep you cool in humid climates and seamless so there are no pinch points. Totally adjustable to give the perfect fit so the pack sits on your hips and doesn't pull on your shoulders at all. The 50L packs were the perfect size for carry-on on every airline, huge money and time saver versus checking luggage! Big enough for a 4 week trip in warm climate - the floating lid means you can really over-pack this beauty as well if you need. Durable, built in rain cover, lots of pockets, hip belt pocket will fit most smartphones for easy access. Awesome pack.

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.
