This is uniquely undertaken for the POLYESTER Dayglow material used inMcWilliam Windsocks.The POLYESTER material is woven specially to our specification for windsock use. Nylon isunsuitable because it fades and rots rapidly due to UV degradation in sunlight. This is especially seenin the Middle East, Far East, North Africa and Central America.Only McWilliam Windsocks are made from the above materials and processes which are speciallyundertaken for our own windsocks.All our windsocks are designed and made using CAD/CAM technology to assure consistency of shapeand size.
