Didriksons Breathable Level Chart

The Breathable Level is achieved using waterproof and breathable fabrics.  If a garment is using waterproof and breathable fabric but the seams are not sealed, this will result in a higher Level number than if if would have had sealed seams, as the seams will let air pass through.  The other factor is the ability a waterproof fabric allows moisture vapour to be transported from the side of the fabric to the outside.  The Level number indicates how many kilograms that will pass through 1m2 (1 x metre squared) during 24 hours.  The breathability can be measured in many different testing methods.  At Didriksons, they use the one called ASTM E-96 BW STANDARD.  It's important to also look at the garments Function Level when you are looking for a garment to be used when you are active, for ventilation etc, as this can help you to keep a good micro climate inside your protective shell.
