Breathability Depends on Water Repellency

Breathable waterproof garments are most likely to become moist inside when used for an extended time in wet conditions. If the outer shell absorbs a lot of water, the garment can lose up to 70% of its breathability. Therefore, maintaining durable water repellency (DWR) in the outer fabric of the garment is essential to ensure its functionality. DWR treatments wear off over time and need to be renewed with suitable products.

Waterproof fabrics must allow moisture vapor to pass through, or breathe, otherwise, sweat cannot evaporate, leading to moisture. If the outer fabric absorbs water and becomes wet, breathability is reduced.
