You may never have realized that this was even missing from your travel, camping or day trips away but let us tell you, it really has been. If you are fed up of diving into that giant full cooler, burying your hand all the way to the bottom to still not find what you are looking for, then welcome the RTIC Ultra-Light cooler divider. This replacement divider is compatible with the RTIC Ultra-Light Cooler. Divide that cooler with an insert, you know it makes sense.
