Capes in Minecraft are rare items that can be worn by the player character in addition to the skin. They have no in-game functionality and are purely decorative vanity items.
Capes in Minecraft have been temporarily given to players on special occasions or permanently awarded to individual players for providing help and ideas to the game developers. Others have been awarded to certain groups of people that were involved in the game’s development. Capes have been given to attendees of several MineCon conventions, either through cards or emails with redemption codes, and all Mojang employees are granted a cape with the company logo on it. Capes cannot be crafted or acquired by a player on his own unless he uses a mod.
