Great for protecting my maps
Size: Regular - 12 x 16 Inches
Fits my exploring maps just right. Heavier duty than expected. Ziplock closure is tight and should last for years.

Terrific addition to your backpacking gear
I like this map holder for its versatility in holding different size maps. Once sealed, it was very effective at keeping moisture out and protecting the maps. I originally used this on a 13K mountain ascent. Worked great. The only thing that can be tricky at times is sealing the top. It's not as easy as sealing a typical zip-loc kitchen bag, takes some doing to get it to seal.

Best Map Case Ever!!!
Size: Regular - 12 x 16 Inches
Best Map case in the market! Field tested and keeps everything dry. The size is fantastic and you can run paracord through the rings. I would recommend this to anyone that uses a map. You definitely pay for what you get and that's high quality and functionality.

Just right for protecting river trip guides
Size: Regular - 12 x 16 Inches
Nice and durable - heavy duty. Getting ziplock to close is a pain though - lick or spit helps.
