I normally inflate mine outside my tarp but if I had to do it while it was raining I would leave the pad outside while I was inside. The pad would be part of the way in. Problem with breathing into one is mold developes. It can lower the R- value on some pad. I have read it will lower the r-value on the xtherm for sure. Thermarest uses reflective material in the xtherm. If mold grows it covers the reflective material and therefore will not reflect. The bag is actually pretty heavy duty. I would use it for a bag liner. It more heartier than say a trash bag
