Difference between a regular ice chest and a marine cooler?

Question

I went to walmart looking for a ice chest and did not find the right size i was looking for but found this marine cooler which was the right size and on special

I wanted to know what is the difference between the two?

Answer 1

I was researching ice chests and believe the difference between the Marine and Regular Cooler/Ice Chest is the seal between the lid and the chest. In the Marine chest there is a better airtight/watertight seal than on the Regular.
