I bought this as a dedicated summertime day-hiking pack for one-day missions. I have to say, this is one of the best fitting packs I've ever owned. It feels like it's hugging me. I got the larger size (female, 5'9', long torso) and I'm so glad I did. The waist belt on many packs creeps up around my belly button, but this one stays put right over my hips. It's not huge, but it keeps me focused in my packing, which is a good thing anyway. I'm really glad I got it and it makes my hikes more enjoyable to have a nicer pack with good pockets and excellent function. I expect I'll enjoy it for many years and miles. Thanks Osprey!
