hey guys i was just looking into fabrics and thought there might be other fabrics people could condiser making hammocks/winter gear out of other than what we currently use, more advanced fabrics. In the process i found some cool fabrics:

Absurdly expensive cycling jacket with crazy warm fabric:
1. http://www.wired.com/gadgetlab/2009/01/bike-geek-gear/

"After all, this is billed as a jacket that can do it all — going from a vest for days in the mid-60s to a thermal wonder that will keep you warm down into the 30s." Appears to be windproof, trap ambient body heat, and repel rain all at the same time. The real interesting thing here is radiation insert: "It looks like a jacket made of space blanket material, shiny and almost paper-like. It’s perforated with thousands of little holes to allow moisture to escape."
