I use this product when traveling in several ways. I like to get into it when trying to sleep on a plane - it packs up so small that it easily fits in my carry-on, and is just enough to keep me feeling cozy when the airline keeps the plane too cold. I also use it when at a hostel and uncertain about the cleanliness. Yes, the fabric is thin, but it is not "porous". Get more detail about Cocoon CoolMax TravelSheet.
