Have you ever found yourself on a street corner or in a car trying desperately to refold a map, bending it this way, then that, accordian folding, then just shoving it closed? And days later, you end up with a hole in the center on the seam. Nice.
This map is the best invention ever! All you do is crumple/shove/stuff it in your bag or pocket and keep moving. It looks like its made from Tyvek-like material. Oh yeah, and it's totally waterproof.
