A personal thermal garment has a shell and a thermal insert that overlay and cover a substantial portion of the back and the chest of a user. The shell has inner and outer layers that are interconnected to define a chamber between the layers, the chamber extending substantially throughout the shell and overlaying a substantial portion of the back and chest of the user. An access opening to access the chamber is provided in the shell. The thermal insert can be preheated to warm the user or can be precooled to cool the user. The thermal insert substantially conforms to the chamber and has a body portion with two leg portions that extend in the same general direction from the body portion. The insert body substantially overlays and covers the back of the user, with one of the two legs extending over one of the user's shoulders, and the other of the two legs extending over the other shoulder. The access opening is sized to have a length that is about the same as a width of the thermal insert, to easily and conveniently insert and remove the thermal insert into and from the chamber. The thermal insert may have two congruent layers and multiple compartments defined between the two layers, with one of the compartments being sealed and containing a thermal storage medium. Alternatively, the insert may be constructed in one, integral piece.
