A notebook that stands up extremely well to bad weather and harsh working conditions
Color: Tan, Size: 1 Pack
Now that I've used this notebook, I can't see myself using any other kind. I travel a lot and need a notebook with me at all times. That means the notebook I have with me is going to get wet frequently and take a beating in my pocket. This notebook is perfect. Rain/sweat have no effect on my written notes or my ability to write. The pages are thick which prevents tearing. The cover and binding are quite sturdy, rather than getting bent like cheaper notebooks. At 4x6 inches this fits in my cargo pocket without a problem and gives me plenty of writing space. If you are going to carry the notebook in your front pocket I'd suggest the smaller 3x5 version. The ruler on the back page was not something I thought about but has come in handy several times. No, this is certainly not the cheapest notebook available, but it is a reasonable price for a high quality product. If you are using this for field work, it is probably worth the cost. My work notes are certainly more valuable to me than the couple extra bucks spent. And really, how often do you fill up a notebook? I only go through one every month or two so it's not very costly. You cannot use gel type pens with this notebook, only normal ballpoint pens or pencils. I suggest using a Fisher Space Pen, it works very well with this notebook (also available on Amazon Prime for under $10)

Wet proof is great
Color: Blue, Size: 6 Pack
As a nurse, I am able to put this in my scrub pocket and make notes as I go along. I also write down my patients' meds so I can refer to it when the computer is not available or not with me. Since it is wet proof I can sanitize it when (and not if) it gets something on it. I use a ballpoint pen and have used a pencil and none of my writing gets smeared or erased by the disinfectant wipes. Since I have these books stored securely in my locker if something comes up in the future with someone I can refer back to them for answers not found in the chart. I use my book when I am giving shift report which is very helpful when I have to tell the know-it-all nurse every little detail because she wants to eat breakfast instead of reading orders and notes. Some of my coworkers have also ordered their own books. A great product and very durable.
