ABSTRACT:
A protective helmet adapted for distributing cooled air to the head of a son comprising an outer shell and an inner lining of open cell foam. A cool air inlet conducts cooled air into the capillary system of the open cell foam where it is distributed throughout the volume of the foam. The cool air exits a multiplicity of pores in the surface of the foam in a randomly oriented fashion, providing cooled air substantially evenly distributed over the head.
