The Coleman 36Qt Xtreme. It is Ideal as a light freezer storage unit. I used the cooler box on 3 flights coming home from Norway with the box full of frozen fillets of fish and it was perfect over 13 hours travel time and all was intact. It Is easy to clean and gives ample storage for frozen goods. The carry Handles makes it easy for one or two people to lift the box when full. A good and robust box for Anglers going abroad.
