Builder's Moisture barrier , thicker, .. or a painters , disposable drop cloth , thinner .

lots of square feet in the package.

get a hole/ tear on the trip, clear packing tape . and then a new piece when you get home.


Smaller than the tent outline or you get a lake on top of the moisture barrier, under your tent.

I used loops of packing tape to hold the plastic on by the stake out loops on the tent.
