Coolers can be made out of plastics and steel. All of them work as expected of them but I would prefer keep marine coolers than plastics. If you ask me why, below will be some of the reasons why I want to keep them.

1. The use of steel allows you to store ice for a longer time. In some of coleman stainless cooler, ice can be stored up to 3 days. The steel gives an extra-thick insulation. Because of this, you have now the luxury of using ice for days even if you are out camping for at least 3 days. You can keep your beverage cool as always while camping.
2. They are now made stainless. Because of this, having stainless steel cooler could be preserved for a long time. It is worth the investment. The steel made had been treated to avoid rust and corrosion. This would also mean, no matter where you go you will always have your coolers looking sleek and nice despite the weather conditions outdoors. The stainless feature adds up to their durability. And mind you, this feature is not only limited to their outer covering but even the hinges and screws are made stainless for these Portable Coolers.
3. They also have the feature of the average coolers. They are still easy to transport. They are still spacious so you can fit bottles or canned drinks in it. They still have those easy grip handles to make it easier for transportation. The seal are still tight-fitting but the only difference is that even the lids are fully insulated to make double the coolness power compared to that of the average cooler. They still have the easy drainage that allows you to remove water without taking the lid off.
4. Everything about it is an improvisation of what we are used to before. They have new solid latch that would allow you to secure the contents of your steel coolers. If in case it gets accidentally tumbled down then you do not have to worry about your drinks getting splattered all around. They are also made to be odor-resistant so you do not have to worry about pungent smells from leftover meals or spilled beverages to stick your coolers.  
5. They come in with years of warranty.
