while exploring the temptrol matreial under discussion in another thread, the thought came to me of using aluminum foil as a liner in the Clark storage pockets which should reflect back your body heat. Has anyone tried it?

I wonder if you used aluminum foil as a liner and then put inflated ziplock bags between the foil and the inside of the hammock - would that keep the heat from the bags and your body from escaping, giving you and effective dead air space? didn't they do something like this in the Apollo 13 return trip?
