Versatile leisure. Made of high-grade PU 210D oxford fabric that feels smooth against the skin, and ensures a moderate thickness and strength. The back is coated with a waterproof coating, making it waterproof and stain resistant. It is flexible like a cloth and can be stored compactly without adding bulk (comes with a storage bag) and is shaped close to a circle, making it perfect for gatherings in many occasions. The hexagonal shape makes it easy to use as a tarp in emergencies. It can be used as a ground sheet for a hexagon type tent, as well as for a typical pentagonal 10.6 inch (270 mm) square tent. When using as a ground sheet, store the fabric protruding from the tent floor under the tent. In order to provide both a super large format and a cost, we have seamed them together.
