Cooler with rubber gasket vs cooler without: Gasket wins for ice retention, but costs more

The rubber gasket creates a tight seal that keeps ice an extra day or two, while plastic-on-plastic coolers let warm air seep in. Gasketed coolers cost more and are best for camping or sun exposure, but for short beach trips or tailgates where you open it often, the gasket helps less. If you want ice to last, buy the gasket; if you’re just keeping drinks cold for an afternoon, save your money.
