CINDY M This is a lightweight ground tarp that is cut to perfectly fit the footprint of the tent. It has been an excellent purchase and I'll look for these in the future instead of standard rectangle tarps.

SunnySports S The one to order is our SKU# ERKFSR2 - EUREKA FLOOR SAVER RECTANGULAR 2X. It is meant to be used UNDER the tent (you will need to fold or cut it to size), but you can use another one inside the tent.
