I unfolded it for the listing, and it worked without any problems. It has wrinkles because I just unfolded it, but they will disappear with time. While inflated, it doesn't leak air, but if you close the valve after deflating it, some air will gradually seep in over time. It's not a problem if you secure it with the band and store it in the bag. Therefore, I'm offering it at a low price. ⚫︎For important sleep during car camping What's important is the thickness of the mat and the right firmness To car camp comfortably, getting quality sleep is crucial.
