Russell's Plantation Series "Zephyr" has been updated by adding 10.10 oz. Martexin wax army duck to the quarters. The wax army green duck gives it a great look and the water repellent finish provides a firm yet supple hand making it water repellent. The leather is a fleshy leather which is an oil tanned leather produced from quality USA steer hides. The oiled surface lubricates the fiber structure for footwear flexibility and function. Double vamp construction for added water protection. The sole is Vibram line lite, which is lightweight and provides a great soft step.
