Our Microtex Uninsulated Jacket is as soft and quiet as fleece, and it is as tough as denim and sheds burs, seeds and leaves. Virtually no other fabric remains as quiet while wit'standing the punishment that a season's worth of contact with heavy brush, wire fences and other in-the-field obstacles can deliver. The key to the unmatched strength and silence of this combed polyester material comes from its low-nap, incredibly tight, microweave construction.
