What is BR2?   

BR2 is a MUSTO waterproof rating for fabric that delivers complete protection in torrential downpour over a prolonged period of time so you stay dry outdoors.

All of our waterproof fabrics are tested and rated for waterproofness after a minimum of 5 wash cycles to ensure they are storm proof, even after you have worn and washed them several times.

Waterproofness is determined with a measurement called a hydrostatic waterhead. This is measured by placing a tube over fabric and pulled tight. The tube is then filled with water until water begins to leak through the fabric after a 24 hour period. The height of the water column, in millimetres, is the hydrostatic waterhead measurement.

Even after the fabric has been washed 5 times, BR2 has a minimum hydrostatic waterhead of 10,000mm and up to 15,000mm. This is a significantly higher waterproof rating than the industry minimum of 1,500mm, and also accommodates for the change in performance when fabric movement and wind is introduced.

Fabrics with a BR2 rating are also breathable to keep you dry and comfortable. 7,000g of moisture passes through the fabric over 24 hours in a controlled test environment, giving it a breathability rating of 7,000g/24hrs.

Watch the video below to discover how the waterproof rating of hydrostatic waterhead is measured.
