When I saw the Ted Bug Net and how simple it was, I thought I would take it a bit further and make a winter sock using the same type of design. The only real difference is for my WBBB I made a static line for the side opposite the entry side. The entry side is 1/8" shock cord. I'm still playing around with dimensions so it's still very unfinished.
The material came from Scott - 1.1 ripstop seconds in green. I used two 100" lengths and simply sewed the 2 pieces together on the bottom.
It's not finished as I'm making a pocket so it will hold a large sheet of IX-like material (floor underlayment) I got at Home Depot - The material is 3/32" thick, so 1 sheet will be enough I hope. It's polyethylene foam with a thin plastic backing. Here's the link http://www.homedepot.com/Flooring-Ha...atalogId=10053
It looks just like IX but much thicker. I tried it out after punching some small holes so air will get out when folding it. After sleeping with the IX last night, at 27*, it's just like the IX only thicker and heavier. I didn't have any condensation issues at all. Rough weight estimate as it is now is about 21 ounces for the whole shebang.
The ridge cap will be the last thing I sew on, so it's not shown right now.
So thanks to Hanginout and Pipsissewa and anyone else involved with the Ted Bug Net. It's a simple and easy to make design.
