Osprey feel-a-like

Hey all, looking for some advice again. went and got fitted out at our local REI yesterday and i tried on a few ospreys and one of their REI backpacks. the ospreys fit like a charm, and the REI bag was too big on my lower back, and felt like it didnt form to it at all, too wide perhaps. Anyways, I know now that Ospreys are most likely a good bet for me, but is there any other bags that fit similarly to them? In particular I like the look of Granite Gear bags. I fit a womens medium (17-18) and have a slender-ish frame. thank you :)

My wife moved from an Osprey to the ULA Circuit last year, with the optional S-curve shoulder harness. She says nice things about the Circuit.

But seriously, pack fit is so important that when you find The One, then run with it.

My newer Osprey Exos 48 fits me like a dream. Love the ventilated back panel. I'm 100% satisfied with my pack and that's saying a lot...I usually buy and sell gear like crazy trying all sorts of combinations. This Osprey pack I have now is a keeper. :)

thanks guys! ill look into the circuit for sure!
