Completely insulated with our lunchbox lining with a practical Velcro closure all the way along the top yes, we made it easy for even the youngest kids to bring Mommy another cold one on the boat or at the tailgating party. We're always thinking about you! ;) Just kidding. But it is a fantastic addition to our assortment. Wash Me! Most of our items are 100% washable. Throw them in the washer on the delicate cycle, cold water, and lay flat or hang to dry!
