When you’re working in the field—whether it’s a tactical operation, an industrial site, or a hunting expedition—your gear needs to perform under pressure. Rain, mud, dust, and rough terrain aren’t just possible—they’re expected. That’s where waterproof ratings like IP67 and IP68 come into play.
These ratings tell you how well a case or piece of gear can withstand the elements. And when you’re relying on your equipment in critical environments, that protection isn’t a luxury—it’s a necessity.
What Are Waterproof Ratings?
Waterproof ratings are part of the IP (Ingress Protection) standard, created by the International Electrotechnical Commission (IEC). These ratings show how resistant a product is to solid particles like dust and to liquids like water.
When a case is marked with an IP67 or IP68 rating, it’s been tested for real-world resistance to harsh elements—exactly what tactical and industrial users need.
Breaking Down the IP Rating System
An IP rating always has two numbers:
-
The first number is for dust and solid object protection (0–6)
-
The second number is for water resistance (0–8)
Dust Protection (First Digit)
Rating | Protection Level | What It Means |
---|---|---|
0–5 | Partial protection | Some resistance to dust or particles |
6 | Dust-tight | Complete protection against dust ingress |
A rating of 6 means your gear is fully sealed against fine dust, sand, and airborne particles—ideal for construction sites, dry terrain, or desert operations.
Water Protection (Second Digit)
Rating | Protection Level | What It Means |
---|---|---|
0–6 | Light moisture only | Safe from rain or splashes |
7 | Submersible (1m) | Protected for 30 mins in up to 1 meter of water |
8 | Submersible (1m+) | Withstands longer/deeper submersion (varies) |
IP67
-
Fully dustproof
-
Waterproof up to 1 meter for 30 minutes
-
Great for wet weather, mud, accidental drops in shallow water
IP68
-
Same dustproof rating
-
Can survive beyond 1 meter, often up to 3 meters or more
-
Suited for extreme, prolonged exposure to water or immersion
The exact depth/duration for IP68 depends on the manufacturer, so always check the specs.
Why It Matters in Harsh Conditions
If you’re working in a warehouse or office, IP ratings might not be your top concern. But in the field, it’s a different story.
You’ll want IP67 or IP68-rated cases if you’re:
-
Operating in rain, snow, or mud
-
Working in dusty, sandy, or windy areas
-
Storing sensitive electronics or mission-critical gear
-
Hunting, patrolling, or camping in unpredictable weather
-
Transporting equipment near rivers, lakes, or coastlines
In these situations, waterproof ratings protect your gear—and your mission.

Real-World Scenarios
-
A tactical case rated IP68 keeps weapons and optics safe during a downpour or water crossing.
-
An industrial tool case rated IP67 prevents dust and mud from damaging high-value equipment.
-
A field electronics box rated IP68 survives accidental submersion during a backcountry expedition.
Quick Reminders
-
Waterproof ≠ indestructible: IP ratings help, but don’t rely on them for continuous exposure unless specified.
-
Saltwater matters: IP tests use fresh water. Rinse off gear after ocean use to avoid corrosion.
-
Always check depth limits: “IP68” doesn’t mean unlimited depth—refer to product details for specifics.
Final Thoughts
Waterproof ratings aren’t just numbers—they’re a measure of your gear’s reliability when it counts most. Whether you’re on a job site, in the wild, or in the line of duty, choosing cases with solid IP ratings like IP67 or IP68 means you’re prepared for the elements.
So next time you’re evaluating gear, don’t just look at size, weight, or design. Look at the IP rating—because in rugged conditions, it could be the most important spec on the label.
