Roll it, fold it or hang it, the NaviTote will keep your Weems and Plath navigation tools in good order. It works beautifully as a navigation tool caddie at the chart table. Made with Tough Duck, a PVC backed polyester duck fabric, for added strength and durability this navigation tool bag incorporates gusseted reinforced pockets and strong hanging grommets. The Navitote is designed with input from the United States military and built to meet demands of everyday use on patrol vessels.
