I use a Therm-a-Rest NeoAir sleeping pad. This is not self inflating, so I have to breathe in to the sleeping pad to inflate it.

Are there any precautions for storing the bag to avoid gnarly bacteria / mold from growing inside the sleeping pad since I'm inflating it with such moist air? Is it enough to just store it with the valve open?

No. It's a good thought, but I have had one that I have inflated by mouth for over 10 years. I usually store it valve open partially inflated. I live in Arizona and the temp in the shed can get to over 150 degrees F some days so valve closed would cause the bubble to pop. It has never given me trouble.

I have heard that this is an issue from people who have never owned one before, and usually as a selling point for solid mattresses. But I have never heard it as an issue from someone who owned one.

  • Do you store it fully laid out? I think if it were rolled tightly, it wouldn't much matter if the valve is open. – Elliott B Oct 5 '17 at 0:28

My understanding that the only time inflating a pad by breath is bad is when it will be used in sub-zero conditions, as the moisture can freeze inside the mattress.
