The FPG ThermaShield is a three layer reflective heat blanket that can be utilized as shade and protection from the elements:
As a poncho
As a shelter
As a blanket
This video features the Survivor Blanket, which is the TWO LAYER

This video is an excellent example of how either blanket can be stuffed in the ruck for a simple "day" op that turns into an overnight
op in any weather.
