The reclosable back-seam bag includes a bag body having a top seal and a bottom seal, and a front wall and a back wall. The front wall is joined to the back wall at the top seal and the bottom seal. A reclosable fastener assembly including two ends, a first continuous elongated profile strip and a second continuous elongated profile strip is included in the bag. The first continuous elongated profile and the second continuous elongated profile provide an airtight and watertight seal upon interconnection thereof. An airtight and/or watertight side seal at each end of the reclosable fastener assembly is also provided. A continuous airtight and watertight lower seal along the length of the reclosable fastener assembly is positioned below the profiles. The lower seal connects the reclosable fastener assembly to the front wall.
