A versatile sheet made of durable and rain-resistant waterproof canvas
This is a canvas version of the famous all-weather blanket. It's about the same size as an all-weather blanket, and when used as a ground sheet, it's comfortable because you won't feel the pebbles on the ground (however, it may get flooded during rainy days). Also, the eyelets are large, so it is possible to peg down with solid stakes. It is useful in situations where nonflammability and a certain degree of hardness are desired, such as placing it under a cot in a floorless tent or under a stove in a tent with a floor. We use water-repellent canvas, so even a little rain won't stain it.
