Gone are the days of cheap Styrofoam coolers that break quickly and barely keep your drinks cold. The science of coolers has taken a leap into the future, utilizing modern designs and manufacturing techniques to produce a product that can keep your drinks and food cold for weeks. The insulation, thickness, and rotomolded construction that is typical of the higher end coolers provides an incredible amount of thermal insulation. Many brands come to the forefront in this category, including RTIC, Yeti, and Pelican. The slightly more budget friendly options like the 65 quart behemoth from RTIC can still stand up well compared to the more costly models from Yeti and Pelican.
