A Grey Alien Mask and Gloves worn during the episode "One Son" from the sixth season of The X-Files. Worn by child actors who were shot with a back light, this costume set features a mask made from slip latex with dark plastic eyes.

The mask has slits above the eyes to allow the actors to see, and also includes small slits in the nose and mouth. The back of the mask seals with Velcro that is hidden by a strip of grey coloured spandex, although this would not have been seen as the alien characters only appear in silhouette.

Paired with the mask are a pair of grey spandex gloves with lengthy rubber fingers that have been glued on.
