No I don't have first hand knowledge, but from the commercial I saw on
these they are sort of like leaky plastic bags (Dialysis bags). As such
they allow the passage of water vapor which has a smaller molecular size
than oxygen. It seems that you would simply reach equilibrium with
conditions outside the bag (you would actually lose water vapor) over
time, and would therefore have lower humidity. Anybody else know
anything about these bags?
