This came up in another thread (http://www.hammockforums.net/forum/s...ad.php?t=25059) but I thought it deserved to be discussed on its own.
After using a weathershield made of insultex for just one night (very toasty) I woke to discover that the IX was soaking wet. Reached in and ran my fingers along it and I could see the water on my hands. This pic shows a couple sheets of toilette paper that I patted on the IX. You can see how it blotted up the moisture.
So, the big question is can we really use IX over down insulation? To me it just doesn't seem to breath well enough to use on the cold side (farthest away from body) of an insulation system. It just acted too much like a vapor barrier.
What's been your experience?
