Cape of Daywalking (3.5e Equipment)
From D&D Wiki
Cape of Daywalking: Capes of Daywalking were designed with the needs of the undead in mind. The capes come in many different fashions and colors, but all serve a single primary purpose: stopping the effects of daylight upon the undead flesh. The cape prevents the wearer from the effects of direct daylight or spells causing artificial light such as Daylight. While designed with the undead in mind, some other creatures have found the capes useful against magical light spells just the same.
