I ordered this pack from iRunFar.com when it was on sale last week. It is way smaller than I expected. I suppose if I had a smaller chest it may have fit. I imagine the correct size would be very comfortable.
I would recommend this size for a petite person only (with a small chest if you are a woman).
Message me if you are interested in buying it. Paypal only, at the sale price I purchased it at: $125 + $5 shipping. Retails at $195.
