Quick brisket question

[Fishonshawn]

I keep reading peoples post on brisket and seeing a lot of you are wrapping it in a towel and then dropping it in a cooler...I've kept them wrapped in paper or foil and put in the cooler but what's the purpose of a towel???

More heat holding around the brisket for the rest.
Use your smallest cooler that hold the brisket
