Now that the hot weather is behind most of the country, this is an excellent time to buy a high-end cooler. There’s down to be a lot of deals. We like the RTIC 65, which appeared in our Car Camping Essentials checklist.
Like the Yeti Tundra coolers, RTIC coolers are roto-molded to ensure that they can keep things cool for days. The Wirecutter’s cooler review said that these coolers kept ice for 10 days.
