I just purchased a "new" used Transpac II from a LDS that was not local to me. It was via the phone and mail and I was told that the XXL would fit me. It looks too big for me according to the DR website as far as how far down the shoulder straps come down. I am just wondering how much it matters how far down the chest strap is and if the straps can be shortened. The pac is comfortable and I can get the straps to lie flat on my shoulders and it fits snug. The waist belt is just below my navel, also, which also seems a bit big. I am wondering because the XL seemed to be a bit small. Am I just between sizes and have to just kind of suck it up or what? Oh, I am 6'3" and about 220lbs. I don't really have a long torso, either. Thanks.
