This is a soft cooler bag made of durable polyester shell with EVA molded top and base. Soft coolers are better than hard cooler cases for many reasons. Being soft you can add a few more drinks to the soft cooler with no problem. The lid and the sides will adjust. Also soft sided coolers are less likely to sweat all over the carpet in your trunk. This particular bag I bought, can hold up to 24 cans.
This cooler has the ability to resist odors where hard coolers tend to absorb them. They are easy to clean, if they do get dirty, you can simply wash them out.
This one also has a mesh zippered compartments that you can put sunscreen, keys, the sunblock or extra cups and snacks. Also has two cup holders on the top to place your drinks.
The bag is light weight and when empty it can collapses down to a flat bag which can be easily stored anywhere.
It keeps food and drinks frozen or warm for many hours regardless of the temperature outside.
