I just got my pack in the mail but will sadly have to return it for a smaller size. The size chart says a medium size pack will fit an 18" torso, however after shortening the straps they were still 3 inches above my shoulders. I'm 5'5", which is the average height for women so if you're on the border between a small and medium with your 18" torso, choose the smaller size.
The pack is an upgrade from my Gregory 60 and it has a lot more room and pockets. The pockets on the hip straps will be perfect for holding those things you need to access frequently (e.g. digital camera, bug spray) and the extra pocket on the front is perfect for storing layers, gaiters, etc. that your hiking partner can get easily for you without having to take your pack off or try to zip closed.
I bought it in red and the color is very nice. It's a deep red that's cheerful, not obnoxious.
