I discovered Rite in the Rain products years ago when I needed to write down the location of equipment at work outside rain or shine. They were a life saver and sure beat trying to write the info down inside a clear plastic bag. Today, I have a new job and I need to keep a notebook in my pocket containing cheat sheets I created to help me when the need arises. Being a humid and sometimes wet environment the conventional notebook began falling apartand my notes began to fade out. Then I remembered Rite in the Rain and once again my notes are safe. I highly recomend this product, it works just as advertised.
