Airweave Portable mini Purchased as a new, unused item on Mercari in December 2023 and used about 4 times for car camping in the winter. I am selling it because I bought a separate air mattress. I slept on the Airweave with an electric blanket on top, and then a sleeping bag, so I don't think there is much sweat or dirt. I have never washed it. If you are concerned, please wash it yourself after purchase.
