The invention relates to a thermal blanket having high insulating properties and durability. The blanket is made of nonwoven, foil, silver foil having Velcro® tapes as closing mechanism. The blanket has a bottom piece extending below the mid piece, intended to be wrapped around the crutch, preferably around the groin, of a patient. The blanket is intended for quick and effective prevention and treatment of hypothermic patients with adverse reduction of the core temperature to less than 35 degrees, for trauma patients and for common prevention of shock at accident sites. The purpose is to give rescue personnel a quick and effective material for wrapping against the cold and which increases the core temperature and therefore the chances of survival for hypothermic patients.
