Understanding Waterproof Ratings: Is 2000mm Waterproof Sufficient?
For many outdoor enthusiasts and everyday users, a 2000mm waterproof rating generally signifies adequate protection against moderate rain and wet conditions. This rating indicates that a fabric can withstand a column of water 2000 millimeters high before water begins to penetrate. While not the highest rating available, it’s often sufficient for casual use and less extreme weather.
What Does a 2000mm Waterproof Rating Actually Mean?
The waterproof rating of a fabric, typically measured in millimeters (mm), tells you how much hydrostatic pressure it can endure before water seeps through. Imagine a tube, one inch in diameter, filled with water and placed on top of the fabric. The rating indicates the height of that water column in millimeters before the fabric starts to leak.
So, a 2000mm rating means the fabric can hold back a 2-meter column of water. This is a common benchmark for many everyday waterproof items. It’s important to remember this is a laboratory test. Real-world conditions can be more demanding.
Is 2000mm Waterproof Good Enough for Different Activities?
The suitability of a 2000mm waterproof rating heavily depends on your intended use and the environmental conditions you expect to encounter. Let’s break it down:
Casual Urban Commuting and Light Showers
If you’re looking for a jacket to keep you dry during your daily commute or a light drizzle, a 2000mm rating is often perfectly fine. It will shield you from sudden, brief rain showers. This rating is common in many fashion-oriented waterproof jackets and everyday raincoats.
Hiking and Outdoor Recreation in Moderate Rain
For day hikes or general outdoor activities where you anticipate moderate rainfall, 2000mm can be sufficient. It will likely keep you dry for a few hours in steady rain. However, if you plan on extended trekking or anticipate prolonged downpours, you might want to consider a higher rating.
Extreme Weather Conditions and Extended Exposure
If your adventures take you into environments with heavy, persistent rain, strong winds, or snow, a 2000mm rating may not be enough. In these scenarios, fabrics with ratings of 5000mm, 10000mm, or even higher are recommended. These higher ratings offer superior protection against prolonged water saturation and significant hydrostatic pressure.
Comparing Waterproof Ratings: What to Look For
Understanding the spectrum of waterproof ratings helps you make an informed decision. Here’s a general guide:
| Waterproof Rating (mm) | Typical Use Case | Breathability (Generally) |
|---|---|---|
| 1,500 – 5,000 | Light rain, casual wear, short outdoor activities | Low to Moderate |
| 5,000 – 10,000 | Moderate rain, hiking, cycling, general outdoor use | Moderate |
| 10,000 – 20,000 | Heavy rain, skiing, snowboarding, serious trekking | Good to Excellent |
| 20,000+ | Extreme conditions, mountaineering, prolonged exposure | Excellent |
Note: Breathability (how well moisture vapor can escape from the inside) is also a crucial factor, especially for active pursuits. A highly waterproof fabric that isn’t breathable can leave you feeling clammy and wet from sweat.
Beyond the Millimeters: Other Factors for Waterproofness
While the 2000mm waterproof number is a key indicator, several other elements contribute to a garment’s overall effectiveness in wet weather:
- Sealed Seams: Even the most waterproof fabric will leak if the seams aren’t properly sealed. Look for taped seams or fully taped seams for the best protection.
- Durable Water Repellent (DWR) Finish: This is a coating applied to the outer surface of the fabric that causes water to bead up and roll off. A good DWR finish is essential for maintaining the fabric’s waterproof and breathable performance. It will wear off over time and may need reapplication.
- Construction and Design: Features like storm flaps over zippers, adjustable cuffs, and drawcords can significantly enhance a garment’s ability to keep water out.
When is 2000mm Waterproof NOT Enough?
You should consider a higher waterproof rating if you:
- Plan to spend extended periods outdoors in heavy rain.
- Are participating in activities where you’ll be in constant contact with wet surfaces (e.g., sitting on wet ground).
- Need protection against driving rain and strong winds.
- Are heading to regions known for consistently wet climates.
People Also Ask
### What is considered a good waterproof rating for a jacket?
A good waterproof rating for a jacket depends on its intended use. For everyday wear and light rain, 2000mm to 5000mm is often sufficient. For more serious outdoor activities like hiking or skiing in moderate to heavy rain, a rating of 10,000mm or higher is generally recommended for better protection.
### How waterproof is 10000mm?
A 10,000mm waterproof rating means the fabric can withstand a hydrostatic pressure equivalent to a 10-meter column of water. This is considered a good level of waterproofing for most outdoor activities, including hiking, cycling, and skiing in wet conditions, offering reliable protection against moderate to heavy rain.
### What is the difference between waterproof and water-resistant?
Water-resistant fabrics repel water to a certain degree, meaning they can handle light moisture or brief exposure to rain. Waterproof fabrics, on the other hand, are designed to prevent water penetration entirely, even under significant pressure, and are typically constructed with membranes and sealed seams for complete protection.
### Is Gore-Tex better than 2000mm waterproof?
Yes, Gore-Tex is generally significantly better than a standard 2000mm waterproof rating. Gore-Tex is a brand of high-performance waterproof and breathable membrane, often featuring ratings well above 20,000mm, combined with excellent breathability, making it ideal for demanding outdoor activities and extreme weather.
### How do I maintain my waterproof gear?
To maintain your waterproof gear, always follow the manufacturer’s care instructions. Generally, this involves washing with specialized technical washes, avoiding fabric softeners, and tumble drying on low heat to reactivate the Durable Water Repellent (DWR) finish. Reapply DWR treatments periodically as needed.
Conclusion: Making the Right Choice for Your Needs
In summary, a 2000mm waterproof rating offers a decent level of protection for casual use and moderate weather conditions. It’s a common and often cost-effective choice for everyday rain gear. However, for more demanding adventures or prolonged exposure to
