摘要
A protective hood, such as a firefighter's hood, has an upper head-covering section, an anterior head-covering section having a window, through which portions of a wearer's face are exposed, a posterior-head covering section, and a lower shoulder-covering section. The anterior head-covering section is made from comparatively heavier, thermally insulative, heat-reflective material, whereas the upper head-covering section and the other sections, or a selected one of the other sections, are made from similar, comparatively lighter material, such as mesh or netting, whereby to allow heat to pass readily through those sections made from comparatively lighter material.
