"The" Standard for All-Weather Notebooks
Color: Black, Size: 3 Pack
This Rite In The Rain notebook is the leading brand for a reason. It works exactly as advertised, performing flawlessly in conditions where a normal notebook would be ruined. I’ve used alternative brands in the past and ran into issues with the paper or ink smudging, but I’ve had no such problems with this notebook. The weatherproof paper and sturdy cover ensure that your notes stay safe and legible, no matter the conditions.

An Amazing product, that works
Color: Green, Size: 1 Pack
I bought the (Rite in the Rain - Green Tactical Note Book (All Weather) for my line of work with the sheriffs department. And when your note taking can be the difference between your job and keeping someone bad off the streets, it's important to ensure that your notes are going not only to last, but handle all situations (like weather). I recieved my notebook about 5 days ago, and decided to give it a try, First I noticed it looked and almost felt like ordinary paper, but with a more thick quality with it. I began to write simple phrases on the first page with a variety of writing utensils, I tried an ordinary pen, a pencil, a 0.5mm pen and pencil, ballpoint pens, and so on. Then I tore out the first page which was as easy if not easier than an ordinary notebook. I took it over to the sink area and began to run water on the paper, for about 2 minutes the water beaded off the paper with ease, i turned the water off and examined the paper, it was only wet on the surface, i wiped the excess water off and perfect, it felt like the original paper with no signs of any water damage. This is a great product for someone who may work in an outdoor environment or just near water I highly Recommend this product to anyone in the market for a notebook that not only has quality but is resistant to everyday situations, thanks (Rite in the Rain) for making a great product. If you have any questions or comments or conserns please use the comment section below, and I will answer as swiftly as I can Thanks.

This is a Great Watch!
Color: Green, Style: Modern
Awesome watch!! I bought this watch three weeks ago, and I couldn't be more pleased. I needed a watch with a rubber strap. I work with natural stone, and the majority of the tools we use are water tools. I have never owned a watch with a rubber bracelet before this one, and I am very impressed with how comfortable and easy to keep clean it is. I also enjoy the green, orange and black color scheme. This watch has held up great! I shower with, swim, and work in this watch. I am very rough on this thing, and so far it has handled everything well. The solar feature works great! I received it with a full charge, and after the first day it dropped to medium. I placed it in a window seal for a few hours, and it has held a full charge ever since. I enjoy how lightweight and comfortable this watch is as well. It fits well on my medium sized wrist, it is not too big and bulky, but it is not a small watch either. The large numbers on the dial glow, and the digital screen has an illumination light. The digital display is kind of small, but the analog is very easy to read. The Arabic numerals are very large making them easy to read. This watch has all the great features you would want from a digital watch, with the style of an analog watch. All of the digital features are easy to use. I have always worn, and preferred an analog watch, so the : stopwatch, dual timers, and alarms have all been nice to have. The watch comes with a manual, but it is kind of small and hard to read. I would recommend going to Casio's web page where you can view, save, and print a much larger and easier to read version of the manual. The manual is easy to understand, and the watch is easy to program. This is my first Casio, and I could not be more pleased! I'm now thinking about investing in a G-Shock. The digital features on this watch have made me want one with a larger digital display, so I am wanting to buy a digital only watch. The GW6900-1 looks cool and is atomic and solar! It is also a good buy at around $79.00 on amazon right now. Check it out too, if you think you want a full screen digital instead, and don't mind spending a little extra cash.
