These waterproof map cases keep your map dry in any weather. Fully transparent and easy to open and close. We have developed these cases with ease of use in mind. They are fully transparent on both sides, so there is no need to take out the map to see the other side which saves valuable time. The small corner openings make it possible to attach the map case to a backpack or on a kayak. The included distance lanyard has two scales on it; 1:25, and 1:50, which facilitates to measure the distance of your hike. Since it's soft and bendable it’s easy to place it directly on to your route on the map. The neck strap also helps to keep your hands free while out on your outdoor adventure.
