I have a 4 piece sleeping bag up for sale here. It is a Military issue sleeping bag. It comes with the stuff sack, gore-tex bivy, heavy wieght liner and the light wieght liner. All 3 pieces snap together and together will keep you very warm in the nastiest weather out there. Packs down to about 1 foot long by about 10" in diameter. All together it wieghs about 9 pounds. Will consider all trades and will sell for $185 TYD with tracking number. PMO prefered. PM for faster response and can email pics upon request. Thanks for looking, Mike.
