With our light, compact emergency shelter, you'll never be without a warm, dry place to crash. Made of a metalized polyethylene film, the triangular cross-section of this shelter reflects up to 90% of your body heat, making the most of your precious warmth. The metalized film is also highly reflective, so it's easy to find in an emergency situation. This shelter is so well-constructed, that it can be used as primary tent while camping, hiking, fishing, and light enough to keep you, your car, boat, or bug-out bag in case of emergencies.
