A Footprint Groundsheet is an optional extra that you can purchase for your tent. It is usually made from the same material as your tent sewn-in groundsheet. The reinforced PVC polyester layer sits between the base of the tent and the ground. It will be the first thing you put down before pitching the tent which acts as a base to stop you getting muddy and wet when kneeling down.

It will keep the groundsheet of the tent clean and will help to protect it from abrasion and damage. It should be entirely covered by the tent to prevent rain from being channeled under the floor.
