Over-roof for the Loire ridge tent. This is a huge piece of shaped cotton that goes over the entire main tent including the curved back and pegs securely to the ground. There is a small air gap between the over-roof and the actual tent, as with all good over-roofs, and this provides additional wind and weather protection. Please note that the additional Loire porch attaches to the over-roof, not to the Loire tent so that needs to be borne in mind when you're buying the add-ons.
