I used this once for camping, but it didn't suit me, so I'm selling it. *I slept with my head on top of the hood, placing it inside the sleeping bag's hood, so my head should not have directly touched it. There are no air leaks. I inflated it with an air pump, so I believe there are no issues with mold or odor from breathing into it. I will pack it in a plastic bag and ship it in an envelope.
