I bought this for a winter trip in the White Mountains. I have large shoulders and narrower waist, so in order to accommodate the fit, I got the large. Unfortunately, it was too long top to bottom, and the pack was too loose up top...too much swaying around my shoulders. Fortunately, I was able to return the pack for medium torso length pack and then exchange the shoulder straps for a larger size. Presto! problem fixed.
I was able to cram all of my gear into this pack. The only gripe that I have is that the sleeping bag compartment was too small to easily fit a long sized, zero degree sleeping bag. Yes, I used a compression sack. I was able to get the bag in, but I was sweating on a 10 degree morning to do it.
All around, awesome pack, though.
