I will be entering a home-made "Emergency - Bail Out Jacket" at the ADZPCTKO gear contest. It is made out of an emergency blanket; that reflective plastic film. I haven't finished it yet, so I don't have a weight yet. It wont be very durable, it will be very light and it will retain heat, shed moisture and be a great rain/snow/wind jacket in a pinch. Strider
