Breathability
In technical materials, breathability refers to the ability to allow water vapour to escape. The fibres wick the moisture away from the skin very quickly. Breathability is measured in grams (g) of water vapour per square metre (m²) over 24 hours. For a breathability of 5000 in 24 hours, for example, 5000 g of water vapour exits through one square metre of this fabric.
