Rite in the Rain notebooks are designed to keep your notes safe - no matter how much water, mud, sweat, and dust you have thrown at you. With multiple sizes and formats available, there’s plenty to choose from, so how do you pick the right one for your role? Here’s a practical, military-focused guide to help you choose which is best for you.
What Makes A Rite In The Rain Waterproof Notebook Great For Military Use?
These all-weather notebook options from Rite in the Rain are built with special long-lasting waterproof paper that stays readable in rain, sweat, and extreme environments. It’s highly durable and entirely impervious to water, which makes it ideal for operational notes, coordinates, sketches, and tactical planning. The covers are tough and durable, too, which you can augment even further with a Cordura Fabric Notebook Cover.
Choosing The Right Size
Here’s a detailed breakdown of the most common sizes of Rite In The Rain Waterproof Notebook, and how each one works can lend its strengths to a variety of different military tasks:
Mini Notebooks
The mini notebook options are unobtrusive yet big enough for crucial notes. They’re ideal for front-line troops, medics documenting vital information, or any role where you need waterproof notes on the move. Compact sizes fit easily into cargo pockets or a chest rig, so they don’t add unnecessary bulk to your gear, and they can be stowed away in convenient places for easy access. If your role is light on note-taking, we wholeheartedly recommend the mini option for its convenience.
Best For:
-
Quick mission notes
-
Patrol checklists
-
EDC pocket carry
-
Immediate reference (frequencies, call signs, map grids)
3” x 5” and 4” x 6” Notebooks
The 3” x 5” and 4” x 6” sizes strike a good balance between space and portability. These are often used as general-purpose field books in many military units (and are frequently chosen for disciplined note-taking tasks). They’re large enough for slightly expanded notes and diagrams but still small enough for equipment pouches. For an excellent middle-of-the-road option, you can’t do better than one of these.
Best For:
-
Standard field notes
-
Briefing logs
-
Tactical sketches
-
Syncing unit data
8.5” x 11” Notebooks
When your notes include detailed patrol debriefs, recording coordinates, or drawing larger sketches, the bigger formats give you more space without sacrificing durability. They’re great for officers, planners, and specialists who need an expanded writing area. They add extra bulk to your gear, for sure, but that’s more than worth the trade-off in organisational and tactical benefits if your role demands the larger size.
Best For:
-
Detailed reports.
-
Reference documentation.
-
Offline maps & sketches.
-
Command and planning logs.
