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.Direct®.
Your raingear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Tech Wash®, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax TX.Direct®, after cleaning first with Nikwax Tech Wash®.
Nikwax TX.Direct® 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.Direct® Spray-On has been specifically designed and optimised 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.
For best results remove all non-washable parts and always clean item(s) first with Nikwax Tech Wash®. No need to dry item(s) before waterproofing.
