Camping mats with built-in pillow

Built-in pillow

— the presence of a built-in pillow in the rug — usually in the form of a characteristic thickening in the area of the user's head. Such a pillow can be used both by itself and in addition to a regular pillow or other impromptu device (like a folded sweater). This function is found exclusively in inflatable and self-inflating mats (see "Type").
