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 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.
