So I have a few other Osprey packs all in size large. The other packs either have an adjustable hipbelt or adjustable shoulder straps (ie moving up and down) and because I am a thick short guy (5'10 190lbs) the larges have always worked for me. Unfortunately I didn't realize this till I got the Mutant in a large and realized that the torso was about an inch or 2 too long for me. Damn. Gonna give the medium a try, maybe i'll have good luck. If not I think I'll hop over to the Variant 37. I have the variant 52 in large for long trips, and it fits great. Holler.
