How to Choose a Waterproof Jacket
How Waterproof is Waterproof?
How waterproof a jacket is will depend on its waterproof rating. The higher a jacket’s waterproof rating the longer the fabric will remain waterproof for.
Waterproofness is tested in the factory to ensure the product meets the British Standard (which must be more than 1,500mm).Waterproof ratings are measured in millimetres using a Hydrostatic Head test.
In a Hydrostatic Head test the fabric is pulled tight under a 1 inch diameter sealed tube of water. This is then observed over 24 hours to ascertain how many millimetres of water the fabric can withstand before it soaks through. The level at which water starts to come through the fabric is the hydrostatic head- measured in mm.
WATERPROOF RATING
A fabric’s waterproof rating is directly related to its ability to withstand water under pressure in a controlled, laboratory setting. In other words, more resistance to pressurized water equates to a higher waterproof rating. Waterproof ratings are measured in two ways:
pounds per square inch (psi)
mm/24 hours
A "mm/24 hours" rating refers to the amount of rainfall a fabric can withstand in a single day. Thus a 10,000mm waterproof rating means the garment can withstand 10,000mm of rainfall in a single day without letting moisture in. The higher the number, the more waterproof the item will be. Gore-Tex®, for example, has a waterproof rating of 28,000mm.
Common water-resistant fabrics can withstand between 3 to 5 psi of water pressure, which is fine for a brief, light rain shower. A Gore-Tex® shell can withstand about 40 psi of water pressure. This higher rating can become necessary if you’re kneeling on snowpack or carrying a heavy pack in the rain, which puts additional pressure on the fabric.
