Your softshell garment 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 SoftShell Proof™, after cleaning first with Nikwax Tech Wash®.
Nikwax SoftShell Proof™ Wash-In is easy and quick to apply in a washing machine, and its highly Durable Water Repellency (DWR) develops on air drying. The washing machine application ensures that the treatment goes right through the garment, treating seams, tapes and cords, as well as the fabric. Also, as the need for tumble drying is removed, this saves energy and protects more vulnerable, older, garments from heat. Nikwax SoftShell Proof™ Wash-In has been specifically designed and optimised for softshell garments; it leaves a flexible water repellent treatment on individual fibres allowing moisture vapour to pass through, maintaining breathability.
