Claim 15:
16. A method of preventing a vacuum in a cooler and maintaining a temperature differential in the cooler, the method comprising the steps of:
providing a vent passage through an insulated peripheral wall of the cooler, the peripheral wall extending up from a bottom of the cooler such that the bottom and the peripheral wall define an interior space of the cooler;
concealing the vent passage behind a latch mounted on the peripheral wall such that when the latch is closed the vent passage is concealed from a user of the cooler; and
blocking the vent passage with an air permeable-water impermeable material layer thereby allowing air flow through the vent passage while preventing water from leaking out of the vent passage.
