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. It will eventually wear off and need to be renewed with Nikwax TX.DirectAR. Your raingear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Tech WashAR, and if it is fairly new, or recently re waterproofed, the Durable Water Repellency DWR will be revitalized just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax TX.DirectAR, after cleaning first with Nikwax Tech WashAR. Nikwax TX.DirectAR Spray On is easy and quick to apply, and its highly Durable Water Repellency DWR develops on air drying. The need for tumble drying is removed, this saves energy and protects more vulnerable, older, garments from heat. Nikwax TX.DirectAR Spray On has been specifically designed and optimized for breathable waterproof garments it leaves a flexible water repellent treatment on individual fibres allowing moisture vapour to pass through, maintaining breathability. The spray on application allows for direct treatment of areas which require it most e.g. elbows and seams on jackets and will not compromise the properties of internal wicking liners.
