Initially issued as a "barracks bag" until the duffle bag was introduced. Then these were used as a laundry bags. Issued to and used by all US Army personnel. These are made from sage green HBT cotton in the same size and pattern as WWII bags. Originals also were made in khaki twill, od3 canvas, od7 sateen, od 7 HBT and blue denim. So if you have seen an original that wasn't HBT, don't have a coronary. There was no rhyme or reason their issue- in other words, there is no airborne model. Approx. size 24" (61cm) wide x 31" (79cm) long.Made in USA, manufactured by ATF.
