Hi, I heard this pack runs a bit small. I have an 18" torso (which I hate because it seems to be the cut-off point for all pack). Does anyone have any experience on whether the S/M or M/L would fit me best?
Unfortunately, you are right on the edge. Osprey is usually good about measurements, but, for some reason, this pack seems to run about an inch or so small. If you have an 18" torso, figure it's at least 19" for the Hornet. The S/M is specced for <19" and the M/L is specced for >19". I suggest the M/L.
