The SPACE Sportsman Hooded Blanket is a by-product of the super-insulating materials originally developed for NASA. A premier accessory for all outdoor activities. Will reflect & help retain over 80% of radiated body heat, providing warmth and protection even in sub-zero temperatures. The four-ply laminated construction and reflective metal surface make this an excellent outdoor safety blanket for personal protection, shelter, ground cover, and visibility. It is also a radar reflector. Colors may vary.
