The various alternatives mentioned in this regard indeed have various results, but according to several empirical studies, the variations are, in practical terms, not significant compared with much more simple measures aimed at protection from the elements.

An exception may be the vapor barrier liner, although the relevant theories from physics, and their implications for practical applications, are extremely complex, and somewhat divergent.

As for "humidity," this is patently a misnomer; the correct atmospheric measure would perhaps be dewpoint, although given my relatively "extreme" lack of experience, I'm not certain what, exactly, is being described.

I also note that with regard to at least one specific scenario mentioned, there is a failure to adequately suggest the simple expedient of a sleeping-bag cover of typical design.

Also, perhaps remarks about Sierra Nevada ski conditions have "little bearing" on the subject at hand, though I'm very pleased that views expressed on this topic don't excite additional comment.
