Flesh mask

The Flesh Mask is a sheath of skin worn by Red Court vampires in order to pass for humans. It is first mentioned in Storm Front.

Description
During times of intense emotion, the vampire's true, bat-like body can be seen wriggling under the surface of the mask.

Older vampires may use this flesh mask as a shield against the sun, allowing them to walk around in daylight without being harmed.

Storm Front
In Storm Front, when Harry Dresden threw the image of sunshine at Bianca St. Claire who was about to attack him, parts of her Flesh Mask were torn off when she hit the old table and shelves.

B is for Bigfoot and Bombshells
In B is for Bigfoot and Bombshells, Svartalves also are capable of using flesh masks to disguise themselves.

Death Masks
In Death Masks, Duke Paolo Ortega removed his true arm from its flesh mask and drew a hidden weapon, thereby cheating in the duel against Harry Dresden.
