The Mag-Tank 2000 uses the same proven, zipper-free magnetic closure as the regular Mag-Tank, but offers a 50% larger capacity. The Mag-Tank 2000 is named after its calorie storage capacity, and its tapered wedge shape gives it an impressive volume while still maintaining a sleek profile at its base. The closed-cell foam-padded bottom and the reinforced side walls of the bag provide protection and structure for food and electronics, allowing for quick one-handed access.
