Dan recommends this one. I bought it, it kept food frozen for 60 hours, as the first hotel we stayed in didn't let us use the freezer. It is a great bag.If you are in Lakewood and need it sooner, I can sell you mine. Was used on one trip only.https://www.amazon.com/gp/product/B000YB6QK8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
