What makes our aviation windsocks different? Two major things make a windsock, its material and its construction. We start off with a premium nylon fabric that is made right here in the USA to our exacting standards. Nylon offers unparalleled windsock durability to the elements and will not become rigid in cold weather, keeping our windsocks extremely responsive in even the slightest of wind. From there it gets urethane coated and UV protected, giving the windsock superior fade resistance and color retention. The material is subjected to a variety of tests by an independent lab to verify its structural integrity and UV resistance. This superior material is then cut and sewn right here in our own facility. Our reinforced double stitched hems and heavy duty brass grommets, assures our windsocks long life reliability.
