The dust & waterproof transparent mapcase is made from UV, tear & crease resistant fabric, with seams as tough as the material itself, built to withstand extreme atmospheric temperatures & repeated use. This versatile mapcase is completely transparent so you can see both sides of your folded map, meaning you don’t have to keep taking it out & refolding it. I have used one of these for years & it is just brilliant! This versatile case is also perfectly suitable for electronic devices such as GPS, mobile phones or MP3 player.
