The Utility pouches were designed to be worn in addition to the universal pouch, it was larger and could accommodate 2" mortar ammunition, grenades, bren magazines, or ammunition etc. It was worn with one pouch to the fron and the other to the rear and was designed to be quickly removed so that it could be passed to those in the section who needed it during a fire fight.
These pouch sets are WW2 dated and in unissued or near unissued condition.
