Heavy Blanket (Comfortarium Cottoxide, 2^C2OCT2O) is a form of blanket that contains a larger than normal amount of the comfortable isotope comfortarium (2^C or CT, also known as heavy thinblankium), rather than the common Cosium-1 isotope (1^C or C, also called warmium) that makes up most of the cosiness in normal blanket.
