A floor liner is the perfect touch for those who want to experience luxury camping. A floor liner goes inside the tent, on top of the floor- not to be confused with a ground tarp that goes outside, underneath your tent. It's like carpeting for your tent. Their floor liners are made with the same Hydra-Shield cotton canvas used on their tent ceilings. Grommets are placed approximately every 24 inches along the outer perimeter, so the liner can also be used as a tarp. Available in several sizes for their various tents.
