Key Takeaways:
- Different Design Philosophies: TerraSlate is a fully waterproof synthetic paper for laser printing. Rite in the Rain is treated paper designed for pencil and pen field writing.
- Construction Determines Performance: TerraSlate's military-grade polymer base is 100% waterproof. Rite in the Rain resists water but does not repel it at the material level.
- Application Fit Matters: Both serve field use but excel in different scenarios, depending on whether pre-printed color output or handwritten field documentation is required.
Two products appear on many field use shortlists for waterproof paper. Both are used by outdoor professionals and emergency responders. Both claim to perform in wet conditions. But they are built from different materials, for different use cases, and different production methods.
TerraSlate produces waterproof, rip-proof synthetic paper made with military-grade polymers that prints on standard laser printers with full color output and survives complete water submersion without degradation.
In this article, we’ll cover what each product is designed to do, how construction differences affect field performance, and the practical factors that determine which product suits each application.
What Each Product is Actually Designed to Do
TerraSlate and Rite in the Rain are both used in field environments, but they are built on fundamentally different design philosophies that determine where each performs best.

What Rite in the Rain is Designed for
Rite in the Rain is moisture-treated paper designed for pencil and ballpoint pen writing in wet field conditions. Its core use case is handwritten documentation — field notes, logbooks, and forms completed outdoors during rain. The treatment repels water long enough for ink to adhere without smearing.
What TerraSlate is Designed for
TerraSlate is synthetic polymer paper designed for laser printing with full color output that survives complete water submersion without degradation. Its core use case is printed document production — maps, guides, safety references, and any document whose content is produced before field deployment rather than written during it.
Where Their Construction Approaches Differ
Rite in the Rain modifies an existing paper fiber base with a moisture-resistant treatment. That fiber can still absorb moisture if the treatment is compromised. TerraSlate replaces paper fiber entirely with a polymer matrix containing no fiber content. For a full overview of what makes synthetic waterproof paper different from treated alternatives, see our dedicated guide.
Why Design Philosophy Determines Field Performance
A product designed for handwritten field notes has a different production workflow and performance ceiling than one designed for full-color laser-printed guides. Choosing between them starts with understanding what the document needs to do before asking which material survives rain better.
How Construction Differences Affect Field Performance
The TerraSlate vs Rite in the Rain comparison comes down to what each material is made of and how those material differences translate into specific field performance outcomes.
- Full Waterproof: TerraSlate's polymer base is 100% waterproof, while Rite in the Rain uses treated paper that resists moisture rather than repelling it entirely.
- Laser Compatible: TerraSlate prints on standard laser printers with sharp toner adhesion, while Rite in the Rain is designed primarily for pencil and ballpoint pen writing.
- Rip-Proof Build: Military-grade polymer construction makes TerraSlate rip-proof, while Rite in the Rain's treated paper fiber can be ripped under sufficient physical stress.
- Color Printing: TerraSlate's matte surface holds vibrant color laser prints clearly, making it well-suited for map and guide formats that require color differentiation.
These construction differences translate directly into different performance ceilings across the field applications for which both products are commonly considered.
Which Field Applications Does Each Product Serve Better
Understanding where each product performs best helps field users, agencies, and organizations choose the right material for each specific application.
Where Rite in the Rain Performs Well
Rite in the Rain is suited for applications where field personnel write on paper in the rain without ink smearing. Field logbooks, handwritten inspection forms, and on-site documentation completed outdoors during precipitation are its strongest use cases. The US Forest Service's USFS fire field information portal reflects the scope of outdoor field documentation that agencies manage across active operations.
Where TerraSlate Performs Better for Field Use
TerraSlate performs better where printed documents must survive field conditions rather than be written during them. Printed maps, safety reference cards, and field manuals perform better on TerraSlate because the 100% waterproof polymer base provides a higher performance ceiling under sustained water exposure. Field agencies such as those represented by BLM public land management routinely deploy this type of printed documentation across remote outdoor environments where material durability is non-negotiable.
Map and Guide Printing Comparison
For printed map and guide applications, TerraSlate's laser compatibility and color output make it the more appropriate choice. Printed trail maps, river guides, and field reference documents require sharp color differentiation that a polymer surface delivers. Browse our field guide printing collection for products suited to these applications. Rite in the Rain is optimized for writing on rather than printing color onto.
Volume Production and Cost Considerations
TerraSlate's compatibility with standard office laser printers enables organizations to produce field documents in-house at scale. This suits agencies and outfitters producing maps and reference materials at scale, while Rite in the Rain's notebook products serve individual handwritten field note needs. For freestanding signage needs at field staging and deployment sites, our A-Frame Signs provide a weatherproof display format suited to outdoor field environments. Engineering and operations agencies that produce large volumes of field documentation can reference the USACE field publications repository for examples of the technical documentation standards these materials are expected to meet.
Practical Differences That Affect the Purchase Decision
Beyond material construction, practical purchasing and production factors determine which product better suits specific field documentation programs.
- Standard Printers: TerraSlate prints on any office laser printer, while Rite in the Rain is optimized for specific pen types for field annotation.
- Color Output: TerraSlate produces full-color printed guides and maps, extending use beyond handwritten field notes to printed document formats.
- Size Range: TerraSlate is available from 8.5" x 11" through 13" x 19" plus A sizes, covering formats Rite in the Rain does not offer in printed sheets.
Understanding these practical differences alongside construction and performance characteristics provides the most complete basis for choosing between the two products for any specific field application.

Frequently Asked Questions About How TerraSlate Compares to Rite in the Rain for Field Use
Can TerraSlate be written on with a pencil or a ballpoint pen in the field?
Yes. The matte surface accepts ballpoint pen and pencil for field annotations and handwritten additions.
Does Rite in the Rain survive complete water submersion the same way TerraSlate does?
No. Treated paper fiber can absorb moisture under sustained submersion, whereas the polymer construction resists it entirely. The waterproofing is the material itself, not a treatment on top of something absorbent. For more on why polymer construction outperforms surface treatments, see our guide on waterproof paper construction.
Which product is better for a field logbook that personnel fill out daily outdoors?
Rite in the Rain suits daily handwritten logbooks. TerraSlate suits pre-printed reference documents and guides.
Can TerraSlate paper be used in a standard three-ring binder for field reference manuals?
Yes. TerraSlate punches cleanly and fits standard binder formats without cracking or fraying at punch holes.
Is TerraSlate more expensive per sheet than Rite in the Rain products?
Per-sheet pricing varies by thickness and volume. TerraSlate's longer working life reduces total costs throughout a document's lifecycle.
