This is a waterproof ground sheet designed by Neighborhood to commemorate our 20th anniversary. It can be used alone as a leisure sheet, or combined with the separately sold quilt blanket. The grommet holes are placed in the same size and position, so you can layer them and peg down the four corners for a comfortable "zashiki" style camping experience or relaxing in the park. The waterproof PVC-coated fabric has a backing to reduce deterioration of the waterproof surface and prevent scratches and stains from use. A dedicated case is included. This item is brand new and unused.
