When choosing the right clothing for wet weather, waterproofness is a crucial factor. Assessing waterproofness often involves the concept of "hydrostatic head." In this blog post, we'll delve deeper into hydrostatic head and why it's essential when selecting your waterproof trail jacket.
What are water columns?
Water columns measure the waterproofness of fabrics and indicate how much water pressure a garment can withstand before it begins to leak. The measurement is expressed in millimeters (mm) and represents the height of an imaginary column of water the fabric can withstand before water begins 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 listed in our windbreaker category for Gentlemen and ladies. -
5,000 - 10,000 mm: Average waterproof
This clothing offers protection against moderate rainfall and is suitable for outdoor activities like hiking and running. It's also perfect for cycling 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 temperate weather conditions. -
15,000 - 20,000 mm: Excellent waterproofness
For extreme conditions, such as heavy rain or snow, clothing with a water column of 15,000 - 20,000 mm is recommended. -
More than 20,000 mm: Waterproof
Clothing with a water column of over 20,000 mm can withstand the most extreme weather conditions, such as heavy rain or storms. This is sometimes a requirement for more extreme trails.

Why is waterproofing important?
The importance of waterproof clothing goes beyond just comfort. Incorrect waterproofing can lead to unpleasant situations like soaked clothing, which can affect body temperature and increase the risk of hypothermia. By being aware of the water column ratings, you can choose clothing tailored to the specific weather conditions you'll be experiencing.
Tips for choosing waterproof clothing
- Consider the activity: Suitable waterproof clothing is available for various outdoor activities. For walking, a more flexible and breathable jacket is preferable.
- 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 water column ratings is essential when selecting waterproof clothing that meets your needs. By considering water column ratings, you can make the right choice and enjoy dry and comfortable outdoor adventures, regardless of the weather.
