Kelty TN 2 Footprint Tent
A footprint is designed to take the wear and tear off the bottom of your tent and keep it in better shape over the long haul. It also provides additional water protection to keep you drier during wet weather. The footprint is designed to specifically fit the bottom of the tent it's made for so that it fits correctly and doesn't have any excess material outside the bottom of the tent. Excess material outside of the tent dimensions will just collect rain water and pool underneath the tent--not a good thing.
