Brand Name : Crucial Vacuum
Keep your vacuum doing its job with a little help from us. Filters make sure the tiny stuff that doesn't stay in the dirt receptacle from spewing back out into the air. This washable filter makes keeping your vacuum happy easy. Every four to six weeks (depending on how much you vacuum), rinse this filter with cool water and let it air dry. That five minutes will keep your vacuum in tip top shape and your air dust free.

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.
