Our spiral-bound guide books are offset-printed on plastic pages. The covers are plastic card stock. The entire books are waterproof and tear resistant. Guide books include mile-by-mile descriptions of campsites, rapids, and points of interest and include many photographs.
If your offset printed map or guide book gets wet, don't worry! It can stay wet without damage. You will eventually want to dry it out with a rag or by turning and air drying each page. The pages won't stick.
You can write on dry plastic pages with an indelible marker like a Sanford Sharpie.
