This intermediate layer (black) completes my 4 piece modular sleeping system. I obtained the bivy cover, patrol bag and compression bag surplus in Ft. Campbell, KY (101st Airborne). I was afraid it was not going to line-up but everything went smoothly. It was MUCH BIGGER and Fluffier than I expected. It is replacing my old 80's Army mummy bag that has given me 40+ years service.
