The easy to use, safe, high performance wash-in waterproofing for softshell clothing. Adds Durable Water Repellency and revives breathability - in a washing machine.

How Nikwax SoftShell Proof™ Wash-In protects.

Nikwax SoftShell Proof™ from Arkwrights 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.

Like all Nikwax products, Nikwax SoftShell Proof™ is safe to use.
