What is a good hydrostatic head rating?
As a rule of thumb guide an hydrostatic head of 3000 is decent waterproofing, however if the jacket is used with a rucksack a much higher value will be needed. e.g. Gore-tex which has a minimum rating 20,000 when the jacket is new.
How much hydrostatic head do I need?
An Hydrostatic head rating of 2000mm means that the column of water was 2 metres (2000mm) tall before the material leaked. In real-world terms, where you have wind and gravity pushing rain into a tent fabric you will need a measurement of around 1000mm to resist light showers.

What is 5k waterproof rating?
5,000mm or 5 metres (16.4 ft) is how far you could fill the tube before it would start to leak through the fabric. So in theory, you could stand out in the rain until 5,000mm of rain fell before you would start getting wet. The second number relates to how breathable the coat is.
What does waterproof 5k mean?
The measurement of water is in millimetres, which is how the waterproof rating is determined. The higher the number, the more waterproof the jacket.

That means a tent with a 2,000mm rating will endure a 2,000mm or two metre column of water bearing down on it before it starts to leak.
