Our windsocks are designed so that they taper from the throat to the trailing end causes the windsock to fully extend when it is being exposed to a wind of 15 knots (is equal to 28 km/hr or 17 mph).
The HA windsock sleeves have been proven to withstand wind speeds in excess of 145
km/h (75 knots). The windsock fabrics have been tested for mechanical strength, UV
resistance and colorfastness by an independent laboratory.
