Rite in the Rain's Black Soft Cover Field-Flex Notebooks are tough, resilient, and flexible. Everything in this bound book is designed to survive Mother Nature's wrath: the cover, paper, and even the glue is weatherproof. Our weather-resistant and archival-grade paper resists stains, survives moisture, and lasts for a lifetime in storage. Our unique field-flex cover material lets mud and water roll right off, protecting your notes in adverse conditions. Field-flex bends easily and then springs back into shape; they fit comfortably into a cramped field bag and won't be any worse for wear. Each notebook contains 100 pages/50 sheets. (No. 778)
