      Not just a liner!

      Went camping and my one-side window zipper broke and could not zip the window shut. So, we used the liner to cover the window on the outside to help keep some heat in the tent as well from the rain. To my surprise, it held up great! I am very pleased with this liner as it has multiple purposes for me to use now.

      Love the material  and ending up using it to help put over the tent widow because the window broke.
