Guide to water column pressureUpdated 6 months ago

Jackets are described by water column pressure, but what does that mean?

Our waterproof jackets are described as being waterproof with a water column pressure of e.g. 5000 mm.

The water column pressure is the amount of water measured in millimetres, which 1 square centimeter of the jacket can withstand before it is breached by the water.

The higher the water column pressure, the more water the jacket can withstand!

Here is a guide:

Water column pressure of 3000 mm: Can't handle continuous rain, but will be able to keep you dry on a walk where it starts to rain lightly.

Water column pressure of 5000 mm: Is good for light rain or heavy rain for a short time.

Water column pressure of 10.000 mm: Can withstand heavy rain for several hours.

Used for high-quality rainwear that must be able to withstand most conditions.
