Our windsocks are made of the finest European materials available.

The Windsock fabrics have been tested for Mechanical strength, UV resistance and color fastness by an independent laboratory. The windsock is constructed to allow water drainage.

The taper of the fabric windsock from the throat to the trailing end is designed to cause the windsock to fully extend when exposed to a wind of 15 knots (28 km/hr or 17 mph).

The HA windsocks have been proven to with stand winds speeds in excess of 145 Km/h or 75  knots (ICAO requirement)
