A floppy piece of fabric isn't going to protect anything and if you want something that is going to hold up for years and years of abuse then something a little more burly should do the trick. Best Made has done just that with their Document Case.
Made from a thick cut of 8.5oz American russet skirting leather, this case will house all your important documents, a tablet, or even a thin laptop. The leather is molded and finished with brass snaps and hand-stitched waxed cord. And like any good leather, it will look even better the more you use it.
