Feature:
1. The first aid blanket can be used as a reflective film to signal the rescuers.
2. In rainy days, the first aid blanket can be used as a poncho; it can be propped up as a canopy.
3. In summer, when parking under direct sunlight, use the first aid blanket to cover the front windshield of the car, which can reduce the heat absorption inside the car.
4. When used in low temperature environment, it can keep 80% of its own heat not to be emitted, and the strong reflection makes it easier for the rescue personnel to find, which is actually a wilderness survival tool.
