Review on 🌟 Arcturus Insulated Thermal Reflective Tarp - Heavy Duty Survival Blanket - 60"x 82". All-Weather, Reusable Emergency Blanket for Camping or Car. Thermal Barrier Blocks Infrared Signature. by Greg Bellman

This tarp definitely helps retain body heat. I break out a sweet dream in it. Smells a little like chemicals from the packaging. Hanging it outside for 48 hours and hosing down a few times will reduce most of the scent. The product comes with a zipped carrying case made of the same material. In my unscientific testing, putting the phone in a case and locking it shut will result in the smartphone potentially losing its data signal and reducing nearby Wi-Fi signal, thanks to the aluminum casing. To me that's a positive aspect of this material, but do with it what you will.
