Why breathability depends upon water repellency
- Breathable waterproof garments are most likely to get sweaty and wet inside when used in damp or wet conditions. If the outer fabric absorbs water, the garment can lose up to 70% of its breathability. Therefore, the Durable Water Repellency (DWR) on the outer fabric of your jacket must be maintained to ensure comfort. Nikwax Tech Wash® will revitalize the DWR and therefore breathability of your garment.
- Waterproof clothing needs to be breathable
- When we work hard, we sweat. The evaporation of sweat cools us down and keeps us comfortable. But, when it rains we want to avoid getting wet, so we put on waterproof outerwear to keep us dry.
- The waterproof fabric must allow moisture vapor to pass through it, or breathe; otherwise our sweat cannot evaporate, causing us to overheat and get wet from condensation. Additionally, if the outer fabric of your garment absorbs water and wets out its breathability will be reduced, causing you to feel clammy and wet.
- Nikwax Tech Wash® will revitalize the Durable Water Repellency (DWR) of your garment preventing water absorption, maintaining breathability and keeping you dry and comfortable.
