Abstract
The invention provides a thermal liner for a protective helmet, a helmet which includes such a liner removably positioned therein, and a container for the freezing and storage of a plurality of such liners. The thermal liner includes a matrix of sufficient length and width which is sufficiently deformable so as to be insertable within a helmet in spaced relation to its inner wall to confrom generally with the contour of the inner wall and to be coextensive with the major portion of the inner wall area. The liner is provided with a plurality of pockets in the matrix each of which is sealed relative to the other pockets. A heat exchange medium, preferably in its frozen state such as ice, is disposed within the pockets of the liner.
