Received my "discount" hammock sock I purchased from Jeff. For the $10.00 purchase price and about $5.00 for modifications, I believe this may become the most versatile piece of gear in my kit. After modification to include a zipper for the head end portion (which make it a little more like his "travel pod") I tried it out for a nap this afternoon. 37 Degrees and breezy. With my synthetic peapod(witch is only good to 50 Degrees or so) and the sock I was very comfortable. All DIY's should try one of these. And Jeff and Risk should market them. Already thinking about a more advanced version if I can find a longer zipper.
