Query: Works well with 16qt Igloo

We bought this to work with out Igloo Ocean Blue Cooler (16 qt). It almost totally fits one side of the cooler (you'd need two of these to wrap the whole way around). That said, I'd prefer getting more smaller ice mats so you can work the mats around the food better instead of just wrapping around the outside. It does stay cool for a long time and you can store it either flat or folded in the freezer so it doesn't get in the way when you're not using it.
