Rainwear

Rainwear plays a crucial role when it comes to staying dry and comfortable in wet weather. A key quality feature of such clothing is its waterproofness, which is measured in the so-called water column (WP). This value indicates how much water pressure the material can withstand before water penetrates. The higher the water column, the better the garment protects against rain, even in heavy or prolonged precipitation. Below you can find out exactly what the WP number means and which values are recommended for different weather conditions.

The water column

The water column (WP ) is a measure of how much water pressure a fabric can withstand before water penetrates. A value of 15,000 mm, for example, means that the garment can withstand the pressure of a 15 meter high water column without getting wet.

The appropriate WP values for rainwear depend on the conditions of use:

From 2,000 mm WP: The garment is considered waterproof and protects against light rain or short showers.
From 5,000 mm WP: Suitable for moderate rainfall and daily use in changeable weather.
From 10,000 mm WP: Ideal for heavy rain and longer stays outdoors, offering reliable protection even in intense rainfall.
15.000 mm and more: Offers very high protection, even in extreme rain and for activities involving a lot of movement or where the material is subject to heavy wear.

Values from 5,000 mm are often sufficient for normal everyday use and moderate weather conditions. For outdoor activities or in regions with frequent heavy rain, rainwear with at least 10,000 to 20,000 mm WP is recommended.

Breathability

Breathability is just as important a factor as waterproofness in rainwear. It describes how well a material allows water vapor (e.g. sweat) to escape from the inside to the outside so that the clothing does not get wet and uncomfortable from the inside.

A garment can have a high water column (WP) and therefore be very waterproof, but if it is not breathable, moisture will collect on the inside, making it uncomfortable to wear. Good rainwear therefore combines high waterproofness with good breathability.

Breathability

Breathability is often expressed in grams of water vapor per square meter per day (g/m²/24h). Values of around 5,000 to 20,000 g/m²/24h are common:

Low breathability (<5,000 g/m²/24h): May be sufficient for short, less strenuous activities.
Medium breathability (5,000-10,000 g/m²/24h): Good for moderate activities.
High breathability (>10,000 g/m²/24h): Recommended for intensive outdoor activities that involve a lot of sweating.

So when choosing a rain jacket, it is important to pay attention to both the water column and the breathability to ensure optimum protection and comfort.
