Quick Answer
Waterproof map cases can protect against water damage, but their effectiveness depends on the quality of the case, the type of map, and the duration of exposure to water.
Case Quality Matters
When choosing a waterproof map case, look for one made from a durable, waterproof material like polyurethane-coated nylon or silicone. A well-made case should be able to withstand immersion in water up to 10 feet deep for several hours. Brands like Sea to Summit and Adventure Medical Kits offer high-quality waterproof map cases that meet these standards.
Map Material and Durability
The type of map used in the case also plays a role in its water resistance. Maps made from waterproof paper or synthetic materials are more resistant to water damage than those printed on standard paper. Look for maps that are designed specifically for outdoor use, such as those made by National Geographic or the US Geological Survey. These maps are often treated with a waterproof coating or lamination to protect them from the elements.
Practical Considerations
In addition to choosing the right case and map, it’s also important to consider practical considerations like map storage and handling. Store your map in a dry, airtight container when not in use to prevent moisture from seeping in. When handling your map in wet conditions, avoid folding or creasing it, as this can create weak points that allow water to penetrate. Instead, use a map keeper or map case with a secure closure to keep your map dry and protected.
