For all Nordisk Legacy cotton tents, you have the option to add an extra groundsheet to protect against dirt and moisture. Only exceptions are Asgard 7.1 and Ydun 5.5 which are both equipped with an integrated groundsheet. All zip-in-floors are tailored to each tent model and can all be zipped in as each tent is already equipped with a corresponding zipline. By adding a groundsheet you avoid moisture coming up from below and thereby improve the living environment inside the tent. It also helps keep the inside nice and clean when glamping.
