The present invention provides systems and methods for decreasing breath condensation on a facial garment or covering. In one aspect, for example, a system for creating a breathing space between a facial covering and a subject's mouth and nose can include a facial covering operable to at least partially encircle at least a portion of a subject's head and/or neck and a facial spacer operable to be removably positioned between the facial covering and the subject adjacent the subject's mouth and nose. The facial spacer is free to move relative to the facial covering when the facial covering is in position adjacent the subject's mouth and nose.
