Headdemock Pillow Petrol by Fatboy®. For all you Headdemock owners, I'm here to help nourish your body by pampering your head like neck masseuse. Attaching me to the Headdemock is easy as holding hands. My name for this soothing softness is... Pillow! I'm made of a very flexible and high quality polyester material with a protective coating so you can worry less about dirt and water while you're kicking back. My chopped foam innards are soothing -- your neck will thank you! It is recommended that the Headdemock is covered when not in use to minimize constant exposure to water or sunlight; fading is possible when left in direct sunlight for extended periods of time.
