The technology used for "space" or survival blankets evolved from an insulation material developed for use by NASA in the Apollo program. The Arcturus Heavy-Duty Space/Survival Blanket features a Mylar reflective side which can be used to reflect heat and keep you cool or to create a radiant barrier to keep you warm. The other side is made of two layers of polypropylene to use as a tarp or shelter. The grommets are specially reinforced for strength.
This blanket reflects up to 90% of heat and is windproof and waterproof. During the hot months when you're crating outdoors with your dog, face the reflective side out to keep sun and heat away. During colder months, cover your dog's crate with the reflective side facing in to keep available heat in.
This blanket weighs 1.4 pounds and comes in its own waterproof carry bag. It measures 60" x 82" (approx. 5 ft x 7 ft).
