Coleman inner sheet, 295x295cm. Purchased new. Used about 3 times. The back is made of thick blue sheet material. It is waterproof and can be used as a mat for purposes other than camping, such as in the event of a disaster. There are some fold wrinkles. It is clean with no signs of use. I am selling it because I no longer have the opportunity to use it. When tightening the drawcord of the outer case, there is a part where the cord and the bag do not slide well. - Brand: Coleman - Size: 295 x 295cm *Ground sheet is not included. *I will fold it as small as possible for shipping. Thank you for viewing.
