Sea to Summit TPU Guide Map Case
Waterproof map case with 4 lash points. The PVC-free TPU material is flexible - not stiff, so you can fold it and roll it without it cracking. It won't crack in extreme cold either. When you close the Ziploc style closure properly this map case can survive submersion.
