Hey guys, this is an interesting thread, and timely, considering that we are about to introduce our own woobie here at Kifaru. We just thought it was about time to breathe new life into the old poncho liner. Here's a link to a thread about it on our message board for those of you that might be iterested:

Air.177: The problem with most sleeping bag liners, is that you have to crawl in thru the top, making entries and exits from your bag a pain in the butt. Silk liners are definately the best for getting the right balance of light weight/size and temperature rating. Have you checked out the Cocoon travel sheets and liners? They offer these in silk and a new ripstop silk. The big advantage with the Cocoon offerings, is that they have a velcro closure side access. This makes for easy entry and exit when in the sleeping bag. These are available in earthtone colors such as their Muddy Elephant, and I think they are coming out in Coyote Brown also. Here's their website with all the info:
