Thermal blankets are specially designed materials that help retain heat and provide insulation. They are often made from reflective materials, such as Mylar, which can reflect body heat back to the user. These blankets are lightweight, compact, and commonly used in emergency situations, outdoor activities, and by first responders to keep individuals warm. In addition to their use in emergencies, thermal blankets are also popular in camping and hiking gear. They can be easily packed and carried, making them a practical choice for outdoor enthusiasts. Their ability to trap heat makes them effective for maintaining warmth in cold environments.
