The Iceolate Tote fits directly inside the cooler's molded interior and allows you to pull your items out of your cooler and drain out any melted water, acting as a normal valve would on an ice chest. Simply lift the tote up with all your food and drinks inside to allow any excess water to drain out within the cooler. Once all the water has been collected at the bottom of the cooler pour it out... and add in a fresh batch of ice. IMPORTANT: Always take your tote out of the cooler to air dry immediately after every use to avoid buildup or staining the fabric of your cooler.
