This large groundsheet has a waterproof backing (undamaged) and a fleece top surface. Picture shows only a quarter of it as laid flat it measures 4 metres x 3.4 metres. It rolls up to a parcel measuring 56 cm by 20 cm across. The labels say 'Outwell' (the make?) and 'Montana 6' (the tent it's designed to fit?)
