Carbon Fiber is a type of Clothing in surviv.io. Carbon Fiber makes the player almost appear fully black, except for equipment.
Carbon Fiber will make the player very visible as the black color contrasts with the green of the map. However, a player will have slight camouflage when next to a barrel, in a Bunker, in a Storm Bunker, in a Hydra Bunker, or when next to or on any dark black objects and areas.
Carbon Fiber will come out of the Barrel Cache, which drops explosives as well.
