I‘ve had many different coolers over the years trying to find a cooler that will retain ice longer noticeably longer than another. Seems to be so many variables in pre-chilling, weather conditions, humidity, sun/shade, quality of ice, times cooler is opened and closed, etc. that it is hard for me to tell what performs the best.
Though there are some definite cons with the rotomolded coolers such as their weight and reduced interior dimensions/volume, there are many pros such as better hinge system, latches, handles, drain plugs, and the most important to me, the rubber gasket seal on the lid. Nothing worse than opening your non-rotomolded cooler after driving down a dusty road and having a fine coat of dust mixed in with your ice and contents. I do think the rotomolded coolers do retain ice a little longer as well…
