This lightweight fabric gets its name from its soft feel and dove-gray color. Elves have made padded armor from this material for centuries, and it is well liked by arcane spellcasters. Thistledown padded armor weighs only half as much as normal padded armor. It grants its wearer a +2 circumstance bonus on Hide checks in areas of darkness or shadowy illumination, as it blends in with the dim background. It is treated as masterwork armor (the masterwork cost is included in the armor's given cost). Thistledown has 2 hit points per inch of thickness and hardness 0.
