After reading the thread on the sleeping pad jacket (which is pretty cool too) and then the comment on the fishnet, I got to wondering about how you might make a thicker layer that would allow for more airspace. More airspace (to a point) should make it warmer. A loosely crocheted "Afghan" type layer came to mind, or maybe fleece with holes punched in it.

So you have a rain/wind proof outer shell, with an thick airspace layer, and the fishnet as in inner layer. That ought to be warm, light, breathable, fast drying and fairly compressible.

I might have to play with this concept a bit. It's just too easy not to.
