PURPOSE: To obtain a simple warm keeping clothing, easy to handle with increased safety, by filling a warm keeping agent in cells provided in the and warm keeping cl othing and utilizing coagulation heat of the warm keeping agent as a wram keeping source.

CONSTITUTION: A warm keeping clothing consists of a shirt 1 with half length sleeves and short pants 2, and these are coupld by magic tapes 3, 3'. Both sides of the warm keeping clothing are made of rubber cloth, and in its appropriate places ce lls 4 are transversely arranged and equipped. The cell 4 is formed in such a manner that a bog body shaped in almost hexagon having its side about 3cm long is transversely arranged at a space of about 1.5cm apart in each row. Between the cells a passage 4a is formed to width about 0.3cm for the warm keeping agent mutually movable, further the cell 4 is expanded to its thickness α about 2cm and its space portion β is glued. And for the warm keeping agent, a compound of freezing point at 29°CW35°C is used in which 2W4wt% glyserinum is added to, for instance, saturated aqueous solution of seacondary soda phosphate at 50°W60°C or to saturated aqueous solution of lithium nitrate at 55°W65°C.
