Be a responsible parent even if your baby happens to be a tent.
You wouldn't put your baby to sleep on the rocky, filthy ground would you? And, since your tent is basically your baby, make sure your Marmot Astral 3-Person Tent has something between it and the ground. The Marmot Astral 3-Person Tent Footprint uses hardy nylon ripstop to protect the floor of your tent from wear and tear and extend its life for years of use. You can even use the foot print in combination with just the poles and fly when you want a stripped down, low-weight shelter.
