Keeps a person very warm.
"I got this emergency thermal blanket last year. During the winter we had a bad cold snap in Iowa, the temperature was like -20 at night for about a week and a half. My house felt cold even with the furnace going. I decided to try out the thermal blanket. I laid it out on my bed and laid on top of this thermal blanket and covered up with my regular blankets. It was so warm and cosy all night long, my cat was even warm! I did that several nights in row and was so happy with this product! So, yes the emergency thermal blanket works great!!!"
