Are you saying that you do not carry any sort of backpack or shoulder bag, but still want to carry paper? I have a water-resistant document-sized bag from Chrome that I could carry over a shoulder and carry paper inside. To keep the paper nice-looking, put it in a manila folder. If you want to carry no bag, but still want to transport paper, is it possible to find a cardboard document tube, cut it to nine inches, roll the paper inside, and put it in a water bottle holder?
