Keeping warm during the cold winter months can be a challenge. Using this technique for your shelter can be the differnce of a comfortable nights sleep versus freezing all night, possibly to death.
Survival Instructor Mors Kochanski pioneered this design. I am sure many others have thought of using some aspects of this shelter without being exposed to his work, but he is evidently the first to be recognized for it.
Cody Lundin and Dave Canterbury used this design on one episode of Dual Survival when they were stranded on an island during the winter.
Here is a video featuring this concept.
