Windsock is a common weather instrument used for measuring wind speed and direction. These instruments are mostly used at airports, seaports and other open areas like highways and mountain regions. Windsocks are sometimes placed in chemical plants as an indicator of gaseous leakage. Windsock , also known as wind cone, is basically a conical tube made of fabric. The conical has opening on each end which allows wind to flow freely through it.

The Windsock is pointed to the opposite side of the wind direction. Wind direction is considered to be the standard compass point and indicates the direction from which the wind originates. A Windsock pointing north actually indicates the southerly wind. The conical fabric structure is placed high on a pole. The angle of a Windsock indicates the wind speed. In low wind the Windsock droops down and in high wind it flies high horizontally. According to the FAA standards, the Windsock will be fully extended by a 15 knot (17mph) wind. The Windsock will adjust itself according to the wind with the influence of a 3 knot (3.5mph) breeze.

Airport Windsock Corporation is one of the largest Windsock manufacturers in USA. The two factors that make these Windsocks special are its construction and the material. These Windsocks are made of premium nylon. Nylon is a durable material and does not become rigid during the wintry seasons. These characteristics of the fabric increase the durability of the Windsocks. Moreover, the urethane coat and UV protection on the Windsock protects it from fading.
