When choosing the right clothing for wet conditions, waterproofing is a crucial factor. Assessing waterproofing often goes hand in hand with the concept of 'water columns'. In this blog we will take a closer look at what water columns are and why they are essential when selecting your waterproof trail jacket.
What are water columns?
Water column measures the waterproofness of fabrics and indicates how much water pressure a garment can withstand before it starts to leak. The measurement is expressed in millimeters (mm) and represents the height of an imaginary column of water that the fabric can withstand before the water starts to penetrate. A millimeter of water column is also referred to as 1 Schmerber.
Classification of water tightness
-
0 - 5,000 mm: Light water resistant
Clothing with a water column of up to 5,000 mm is suitable for light rain showers. This level of waterproofness is ideal for everyday use or your training run in the drizzle. These jackets are in our category windstoppers for Gentlemen and ladies. -
5,000 - 10,000 mm: Average waterproof
This clothing offers protection against moderate rainfall and is suitable for outdoor activities such as walking and running. You can also wear it on your bike to work. -
10,000 - 15,000 mm: Highly water resistant
Ideal for more intense showers, this clothing is suitable for activities like a long trail or hike in moderate weather conditions. -
15,000 - 20,000 mm: Excellent waterproofness
For extreme conditions, such as heavy rainfall or snow, clothing with a water column of 15,000 - 20,000 mm is recommended. -
More than 20,000mm: Waterproof
Clothing with a water column of more than 20,000 mm can withstand the most extreme weather conditions, such as heavy rain or stormy weather conditions. On more extreme trails this is sometimes a requirement.

Why is waterproofing important?
The importance of waterproof clothing goes beyond comfort. Incorrect waterproofing can lead to unpleasant situations such as soaked clothing, which can affect body temperature and increase the risk of hypothermia. Being aware of the water column ratings will help you choose clothing that is tailored to the specific weather conditions you are in.
Tips for choosing waterproof clothing
- Consider the activity: For various outdoor activities, there is suitable waterproof clothing available. For walking, a more flexible and breathable jacket is nice.
- Breathability: So choose clothing that is not only waterproof, but also breathable to wick away moisture from within.
- Maintenance: Regular maintenance, such as re-impregnating the fabric, extends the life of waterproof clothing. However, we never do this with our jackets.
Conclusion: Understanding hydrostatic head ratings is essential when selecting waterproof clothing that suits your needs. By taking hydrostatic head ratings into account, you can make the right choice and enjoy dry and comfortable outdoor adventures, no matter the weather.
