Waterproof Rating & Breathability
Why Waterproof and breathability ?
For any type of outdoor activity, you’ll want something waterproof and breathable.
Waterproof so you stay dry, and breathable so you don’t overheat.
A good rule is, the more you’re working, the more breathable your garment should be.
Waterproof Rating
Waterproof Rating is expressed as the height of the column of water that the fabric can withstand. The height of the column of water is measured in millimetres
A waterproof fabric must withstand a 1,300 mm column of water, but most manufacturers apply a higher limit of 2,000 mm. At levels exceeding 10,000 mm breatheability values can no longer be distinguished as these are all clearly adequate.
Breathability Rating
A fabric’s breathability rating, represented in units of g / m² / 24hrs, tells how many grams of water vapor pass through a square meter of fabric in a day, in labratory tests. A fabric with a rating of 6,000 g / m² / 24hrs is considered highly breathable,for example the Kingcamp Edge 3P jacket .
