Waterproof in a Viking garment is 8,000 g/m²/24hours

Viking uses the most globally recognized Hydrostatic Water Pressure
testing method – AATCC 127 to qualify our fabrics as being waterproof. The 5,000 - 8,000 g/m²/24hours = Good breathability
test material is subjected to steadily increasing water pressure on one face 8,000 - 15,000 g/m²/24hours = Very good breathability
