"The result of Kilton's research into monsters. Looks like your average leg wear at first, but these were created based on the image of a monster born of darkness."
— In-game description

The Dark Trousers are an item from The Legend of Zelda: Breath of the Wild. It is a leg armor that Link can purchase from the Fang and Bone shop for 1,999 Mon. It consists of trousers created as a result of Kilton's monster research and based on the image of a monster born of darkness, implied to be Dark Link or one of its incarnations. It is part of the "Dark" armor set which makes Link look like Dark Link when worn with the other two pieces. Wearing all three pieces grants a Night Speed Up bonus that increases Link's movement speed during nighttime.
