Overall this product works by forming a barrier bewteen the ground..tree stand..etc and your body. It itself does not produce  heat it simply forms an insulated barrier

Now..the main area that needs to be addressed is the construction. If you buy the 1.5 inch model like I did you will quickly realize it's two pieces glued together....hmmmm. Right out of the box I notirced that was not the greatest idea as mine was peeling away from the corner. I had to superglue the areas coming apart.

Does it work...yes. Could it be better design..yes.

Time will tell how long it will last.
