I noticed in this photo that the survivors of the boat that sadly sank with up to 600 Libyan refugees aboard were issued emergency blankets like those we use in our LifeSecure Emergency Kits. These thermal emergency blankets truly can be a lifesaver and are light, compact, and inexpensive. They reflect back up to 80% of body heat and are windproof and waterproof.
These compact emergency thermal blankets should be a staple in your emergency kit.
