When you’re out in nature—whether camping in the woods, fishing by the lake, or hiking through the mountains—weather can be unpredictable. Rain, splashes, or accidental drops in water can easily damage outdoor equipment if it’s not designed to resist moisture. That’s why waterproof performance has become one of the most important considerations when choosing outdoor products.
In this guide, we’ll explain what waterproof ratings actually mean, explore how different types of outdoor gear are protected, and help you decide what level of water resistance is right for your next adventure.
What Do Waterproof Ratings Mean? (IP Standards Explained)
The waterproof performance of many outdoor products is measured using the Ingress Protection (IP) system. This rating is expressed as two digits:
- The first digit measures protection against solid particles like dust.
- The second digit measures protection against water.
For example:
- IPX3: Protected against light spraying water.
- IPX4: Resistant to splashes of water from any direction.
- IPX5: Can withstand water jets.
- IPX6: Resistant to strong water jets or heavy rain.
- IPX7: Can be submerged in water up to 1 meter for 30 minutes.
- IPX8: Designed for continuous immersion beyond 1 meter.
It’s important to note the difference between water-resistant (can handle light rain), splash-proof (resistant to water splashes or jets), and fully waterproof (can survive immersion).
Waterproof Performance Across Outdoor Products
Tents
Most tents are not given an IP rating but instead are measured in millimeters of hydrostatic head (e.g., 2000mm or 5000mm). This tells you how much rainwater pressure the fabric can resist before leaking. A tent rated 3000mm is suitable for heavy rain, but no tent is truly waterproof under all conditions. They are meant to withstand storms, not submersion.
Backpack Rain Covers
Backpack rain covers are typically IPX3 to IPX4, designed to shed rain and protect your belongings from splashes. They are lightweight and packable, making them an essential accessory for hikers in unpredictable weather.
Fishing Lights & Headlamps
Since these are often used in wet environments, fishing lights and headlamps are usually rated IPX5 to IPX6. This makes them safe against heavy rain, splashes, and even strong water jets. However, most are not suitable for diving or prolonged underwater use.
Outdoor Power Banks
Portable power supplies, like those produced by Merpower, are built with outdoor use in mind. Many models feature splash-proof and dustproof designs with ratings such as IP63 or IP64. This means they can handle rain, accidental splashes, and dusty conditions without issue. They are not designed for full immersion, but they are rugged enough for camping, fishing, or long trips in the wild.
How Waterproof Should Outdoor Products Be?
The right level of waterproofing depends on how and where you plan to use your gear:
- Camping Gear (Tents, Backpacks): Water-resistant or IPX3–4 is generally enough to handle rain showers.
- Lighting Equipment (Headlamps, Fishing Lights): IPX5–6 ensures reliable performance in wet conditions.
- Electronics (Power Banks, GPS, Phones): At least IP63–64 for splash and rain protection.
- Professional/Extreme Use: IPX7–8 for activities where immersion is likely (kayaking, diving, rescue work).
Practical Tips for Outdoor Enthusiasts
- Don’t assume waterproof means indestructible—always check the rating.
- Use dry bags or pouches for extra protection of electronics.
- Combine gear smartly (e.g., a splash-proof power bank inside a rainproof backpack cover).
- Be aware that terms like “weatherproof” or “water-repellent” are often marketing claims, not technical ratings.
Conclusion
Waterproofing is not a one-size-fits-all feature. A tent designed to withstand heavy rain may not keep your gear dry if submerged, while a power bank with IP64 protection can survive splashes but not underwater use. The key is choosing the right level of waterproofing for your activity.
For most outdoor scenarios like camping, fishing, and hiking, IP63–64 is sufficient for electronics such as power banks, while headlamps and fishing lights should target IPX5–6. For extreme adventures, higher immersion ratings may be worth the investment.
By understanding waterproof ratings, you can choose gear that keeps you safe, dry, and powered—no matter where your journey takes you.
