Heated or cooled item of clothing

Abstract

A heated or cooled item of clothing ( 1;15 ), comprising a cartridge ( 4 ) made of two compartments ( 5, 6 ), separated by a divider ( 7 ) that can be easily broken or removed, each compartment containing a substance which, coming into contact with the other, triggers an exothermic or endothermic reaction, respectively. Said item of clothing may be shoes ( 1 ) or women's elegant shoes, or clothes ( 15 ).
