Spiky Diamond updates the sockBack to the 80's on the Oregon coast. In the golden days of spinning windsocks, they filled the sky along the Oregon coast. Much fancier than traditional ones, the Spiky Diamond Sock is sewn of nylon taffeta and fully hemmed. Showy and compelling, it's designed to be flown from a kite not from a pole. 3' x 12', a 9-ft. Delta or Parafoil 7.5 will lift it.
