a crinkly silver sheet that hoards your body heat like a paranoid dragon.
means A thin reflective sheet that traps and reflects body heat back toward you, used to prevent or treat dangerous heat loss in emergencies and after endurance events.
from "Thermal" comes from the Greek thermē, "heat" — the same root behind thermometer and thermos. "Blanket" traces to the Old French blanchet, a diminutive of blanc, "white," originally a piece of undyed white woollen cloth. The reflective foil version owes its existence to space-age materials research: the thin metallized film, sometimes called a "space blanket," emerged from work on aluminized plastic sheeting developed in the 1960s, and the name stuck once it crinkled its way down from orbit to marathon finish lines and first-aid kits.
