Embodiments provide a weather resistant slide fastener with a modified slider body including a top control rib and tightly controlled inner dimensions. In embodiments, a water-resistant coating and/or an adhesive may be applied to the zipper tape, resulting in a highly water-resistant zipper and finished garment. Embodiments further provide a slider body that may accommodate longitudinal edge portions of the outer layer of fabric, allowing the edges of the fabric to be brought into close proximity/contact, substantially covering the zipper teeth and minimizing ingress of water and/or wind through the zipper tape. Additional embodiments provide methods of manufacturing and installing weather resistant slide fasteners.
