Wow that is an excellent deal!
It is important to note that these bags are NOT for those with broad shoulders...I have one and cannot zip it up.
I just measured my chest at about 50"...not sure if that helps. I weigh 250lbs right now. Back when I originally bought my bag I weighed around 230lbs and could get it zipped up with the help of someone else...but it was mega tight. During my last solo canoe trip this past October I could not zip up the bag for the life of me.
It's too bad really because I have the whole system plus the U.S. Winter Bivy Bag that can hold it all...I have used the whole outfit except the gore tex bivy that comes with the bag once in freezing rain conditions and was very warm...I was able to zip up the bivy bag which is oversized to accomadate the sleeping bag but the bag itself remained unzipped past my upper waist...lol.
air force issued me one d I have never used it. I would like to sell it to you but they will probably want back some day.
