BR1 is a Musto waterproof rating for fabric that delivers complete protection in a persistent downpour so you stay dry outdoors.
WHAT IS BR1 FABRIC?
Musto BR1 is a technology used across many active sports disciplines; including clothing for equestrian, sailing and country pursuits such as shooting. From the seas to the city, BR1 fabric performs as a reliable outer or mid layer to protect against unpredictable weather. The technology is utilised across mid and outer layers; including jackets, trousers, breeks and salopettes.
Musto tests how waterproof its fabric is by using a hydrostatic waterhead. This is measured by pulling BR1 fabric tightly over a tube. The tube is then filled with water. The amount of water that leaks through the fabric after a 24 hour period is then measured. The height of the water column, in millimetres, is the hydrostatic waterhead measurement.
BR1 is a Musto waterproof rating for fabric that delivers complete protection in a persistent downpour so you stay dry outdoors.
EXCEEDING INDUSTRY STANDARDS
Even after the fabric has been washed five times, BR1 has a minimum hydrostatic waterhead of 5,000mm up to 10,000mm. This is a significantly higher waterproof rating than the industry minimum of 1,500mm.
BR1 fabrics allow 5,000g of moisture to pass through it, giving it a breathability rating of 5,000g/24hrs.
