A 2000mm waterproof rating is generally considered good for everyday use and moderate weather conditions. It offers solid protection against rain and splashes, making it suitable for many outdoor activities and apparel. However, for extreme or prolonged exposure to heavy rain, higher ratings might be preferable.
Understanding Waterproof Ratings: What Does 2000mm Really Mean?
When you see a waterproof rating like 2000mm, it refers to the hydrostatic head test. This test measures how much water pressure a fabric can withstand before it starts to leak. Essentially, a 2000mm rating means the fabric can hold a column of water 2,000 millimeters (about 79 inches) high before water penetrates it.
This rating is a crucial indicator of a material’s ability to keep you dry. It’s a standard measurement used across the outdoor gear industry, from jackets and trousers to tents and backpacks. Understanding this number helps you make informed decisions about the gear you choose for your adventures.
Is 2000mm Waterproof Enough for Heavy Rain?
For moderate rain and typical downpours, a 2000mm waterproof rating is usually sufficient. It will keep you dry during a casual walk in the park or a light shower while commuting. Many everyday raincoats and some lighter hiking gear feature this rating.
However, if you anticipate facing prolonged, heavy rainfall or being in exposed conditions for extended periods, you might want to consider higher ratings. Think of situations like multi-day trekking in a rainforest or enduring a storm at high altitudes. In these scenarios, a fabric with a rating of 5000mm, 10000mm, or even higher would offer superior protection.
What Other Factors Contribute to Waterproofness?
While the waterproof rating is a primary concern, it’s not the only factor determining how dry you’ll stay. The construction of the garment or gear plays a significant role.
- Sealed Seams: Even the most waterproof fabric will leak if the seams are not properly sealed. Look for taped or sealed seams, especially in critical areas like shoulder seams and zippers, to prevent water ingress.
- DWR Coating: Many waterproof fabrics have a Durable Water Repellent (DWR) coating. This causes water to bead up and roll off the surface, preventing the fabric from becoming saturated. A good DWR is essential for maintaining breathability and preventing that "wet" feeling.
- Zippers and Closures: Water-resistant or waterproof zippers, along with storm flaps, are vital for keeping water out. Loose or standard zippers can be a weak point.
- Breathability: This is often overlooked but is crucial for comfort. A highly waterproof fabric that isn’t breathable can trap moisture from your body, making you feel clammy and wet from the inside. Look for fabrics with a good breathability rating (often measured in g/m²/24h) alongside their waterproof rating.
Comparing Waterproof Ratings: A Quick Guide
To help you visualize, here’s a general guide to waterproof ratings and their typical applications:
| Waterproof Rating (mm) | Typical Use Cases | Level of Protection |
|---|---|---|
| 1,000 – 5,000 | Light rain, everyday use, splash protection | Basic protection, suitable for short exposure |
| 5,000 – 10,000 | Moderate rain, hiking, cycling, general outdoor activities | Good protection for sustained moderate rain |
| 10,000 – 20,000 | Heavy rain, trekking, skiing, snowboarding | Excellent protection for prolonged heavy downpours |
| 20,000+ | Extreme conditions, mountaineering, expedition use | Maximum protection against severe weather and pressure |
As you can see, 2000mm falls into the basic protection category. It’s a good starting point for many users but may not be enough for those who regularly face challenging weather.
When is 2000mm Waterproof Sufficient for Your Needs?
Consider your typical outdoor activities and the weather you usually encounter. If you primarily need protection for:
- Commuting in light to moderate rain: A 2000mm jacket will likely suffice.
- Occasional day hikes in fair weather with a chance of showers: This rating can offer peace of mind.
- Gardening or other light outdoor chores: It provides a good barrier against splashes and light rain.
- As a backup layer for unpredictable weather: It can be a useful addition to your gear.
However, if your activities involve extended periods outdoors in consistently wet environments or if you are a serious outdoor enthusiast who pushes boundaries, investing in gear with a higher waterproof rating is advisable. This ensures you remain comfortable and protected, allowing you to focus on your adventure rather than the elements.
People Also Ask
### What is a good waterproof rating for a rain jacket?
A good waterproof rating for a rain jacket depends on your intended use. For everyday use and light rain, 2,000mm to 5,000mm is often sufficient. For more serious outdoor activities like hiking or skiing in heavy rain, look for ratings of 10,000mm or higher to ensure reliable protection.
### Does 2000mm waterproof mean it’s also breathable?
No, a 2000mm waterproof rating does not guarantee breathability. Waterproofness and breathability are separate properties. While some fabrics offer both, a high waterproof rating doesn’t automatically mean it will allow moisture vapor to escape. Always check the breathability rating (e.g., g/m²/24h) if you need a garment that keeps you dry from both rain and sweat.
### How long will a 2000mm waterproof jacket last?
The longevity of a 2000mm waterproof jacket depends on its construction, care, and how often it’s used. The waterproof coating and DWR treatment can degrade over time with wear, washing, and exposure to UV rays. Proper care, including regular washing and reapplication of DWR, can extend its effective lifespan significantly.
### Is 5000mm waterproof better than 2000mm?
Yes, 5000mm waterproof is significantly better than 2000mm. It indicates that the fabric can withstand twice the water pressure before leaking. This means a 5000mm rated item will offer superior protection during moderate to heavy rainfall compared to a 2000mm rated one.
In summary, a 2000mm waterproof rating offers basic to good protection suitable for many common scenarios. However, for demanding conditions, always consider higher ratings and the overall construction of your gear.
