Best Mylar Blankets for Emergencies

A heat-trapping  mylar blanket should be part of every pack, first aid kit, and emergency readiness bag. Spending a night outdoors without proper gear, even in mild weather, can cause hypothermia. Mylar blankets reflect up to 90 percent of radiant body heat back onto the person. They also fold up small and are lightweight, so there’s no excuse not to have one as part of your emergency kit. In any emergency with exposure to cold, like being lost in the woods, falling into a body of water, or extreme blood loss, a mylar blanket can be a lifesaving tool. Make sure the blanket is big enough to accommodate the user, packs up small, and there’s one for everyone in your group.
