Looking for a small zip up data book cover for my Impact Data Book in pocket size. I want it to have a space to slide in the FDAC, Mildot Master, small Write in Rain notebook, couple pens, mechanical pencil and a mini solar calculator. I have a larger one that has like 3 inches too much fabric that is long and wasted. Hopefully I could get all this squeezed into a cargo pocket when zipped. My current one is just too long. Anyone know something out there that fits this need?
