If you canoe, 4-wheel, hunt, hike, drive or just go outside - this is an essential item! With our Polarshield Emergency Blanket, you'll always be prepared for an emergency or a change of plans. The underlying space-age technology of this blanket reflects your body heat back to you - keeping you warm. Since it's wind-proof, waterproof, durable, and equipped with grommets, this blanket can also serve as a shelter. Better, it features highly visible orange and reflective surfaces for use as signaling tools. Blanket, shelter and signal - all in one compact package - see why we said that it's essential?
