Zelph: In responce to your point reguarding the breathable liner, you ask a good question; and the only way I can rationalise it is the quilt/sleepingbag wicks the moisture away from our bodies. A way to illustrate this is with running clothes techniques. Runners often will wear two tops, even when its warm out. The reason is the first layer wicks the sweat away from the body to the air between the first and second layer where the trapped body heat, heats it up so it evaporates through the second layer. Taking this into consideration I would rather have a breathable liner so that the moisture has a chance to evaporate away from the quilt/sleeping bag. Isn't this how gortex works? Think of the membrain as a finely knit screen, the water drops are too large to get through the individual squares, but water vapor has no problems waffing through.

Thanks Jester. That's a good way of looking at how it works for us. Interesting info there on runners wearing 2 tops.

I'm going googling for a diagram of gortex structure 8-)

Found one and some info:

Early Gore-Tex fabric replaced the inner layer of PU with a thin, porous fluoropolymer membrane (Teflon) coating that is bonded to a fabric. This membrane had about 9 billion pores per square inch (around 1.4 billion pores per square centimeter). Each pore is approximately 1/20,000 the size of a water droplet, making it impenetrable to liquid water while still allowing the more autonomous water vapour molecules to pass through.


I edited this post to add this great site for explanation of the Gortex

Walmart. Get the best you can afford in the temperature range you'll be using it in. I prefer a quilt in moderate temperatures and the bag in COLD climates.
