When Mother Nature conspires to drive you off the course, fight back with Gore-Tex! The fully laminated, lightweight, seam sealed, Gore-Tex 2-layer shell is 100% waterproof and won't absorb moisture in the outside layer. Therefore, you stay dry in even the wettest conditions. Plus, since it is 100% breathable, you stay cool in warmer weather; warm in cooler weather. Softer shell fabric reduces distracting rustle. Nylon mesh liner provides ventilation with a smooth inner taffeta liner below the elbow to prevent snags. Front zip vents adjust airflow without interfering with arm motion. Storm flaps have hidden snaps to streamline appearance and protect zippers from the elements. Full-length two-way front zippers lay flat while putting or simply driving in your car. Flattering over-the-hip shirttail waist is also gathered in the center back to give you a shapely, feminine silhouette. Non-binding cuffs have an adjustable Velcro tab
Gore-Tex. The #1 fabric for the outdoors.
