I am having a lot of trouble finding a pack to fit. I'm 5'5", 110 pounds and very boney in shoulders and hips. I usually pack up to 50 lbs on multi-day hikes (I carry my stuff and my large 8 year olds stuff, too plus dog's stuff and a bear canister and 200 oz of water for everybody in dry areas). Also, a lot of hipbelts are just too big for my 25" waist and my hips aren't much bigger at 30", but I have a 17 1/2" torso so xs bag don't work. My current bag slides all over cinched all the way down--kelty coyote 4750, size small, but I do like the padding on the shoulder straps and cargo size is good. Just need less girth on hipbelt and more shoulder comfort. The osprey ariel didn't feel good at all on my protruding clavicles nor the deuter act 60, aura, jade, rei flash and ridgeline, diva, nor go lite quest. any pack suggestions other than the standard "pack less"?
