Abstract: This invention is directed toward a carrying bag, suitable for carrying one or more fragile items for which a snug fit in the bag is desirable. The bag has a single zipper that extends down one side and across the bottom, and the two halves of the zipper are connected with a pleat, which expands the volume of the bag when it is unzipped. In the middle of the bag is a baffle that rests on one side of the bag when it is in its single-bottle configuration, but separates two items when the bag is in its two-bottle configuration. The bag has a hand loop and a shoulder strap for ease of carrying, several zippered pockets for storage, and a cinch toggle drawstring around the top of the bag for easy and adjustable closure.
