what to use for a floor in a pop up

[fish Hooked]

Bought my first Eskimo fatfish pop up and have heard that some people put a floor in them looking for some ideas on what to use for a floor to insulate from the cold, your ideas please? thanks

My buddy uses big rubber entry rugs, he rolls them up and wraps them with a bungy cord for transport.

What Surf said or I've heard people say to use those rubber snap together gym mats

I use a thick layer of ice!!!

The rubber puzzle mats are supposed to be good.
Be sure to put a tarp down first to keep them from freezing to the ice.
