Abstract
A helmet has an outer shell, an inner lining configured for thermal communication with a wearer's head, an intermediary layer disposed between the outer shell and the inner lining with a layer of insulating material with a plurality of passageways therein and a cavity defined by the outer shell and the outer surface of the intermediary layer, and a fluid contained between the outer shell and the inner lining. In another variation, the insulating material includes a shape memory polymer operable to change the size of one or more of the plurality of passageways when activated. In yet another variation, the helmet has one or more selectively closeable pores in its outer shell and may have a fixed or detachable fluid reservoir.
