CORDURA CORDURA is a material manufactured and sold by Invista, an American company. It seems to be a high-performance, high-strength material. It's a cool, vibrant blue, and the wide zipper opening makes it easy to put things in and take them out. The handle is also large, making it easy to carry by hand, making it a truly high-performance bag. I received it, but I only tried it on and have been storing it. It's the perfect backpack for casual use, so I hope someone cool will use it well.
