- Owners of breathable waterproof garments who want a treatment listed as compatible with GORE-TEX, eVent or FutureLight.

## Less suited to

## Customer feedback

Customer feedback highlights perceived cleaning effectiveness, ease of use and value, including a report of good results on GORE-TEX fabric. Waterproofing results are mixed, with some customers reporting no effect. For buyers choosing this as a garment reproofer, that uncertainty matters more than its wash-in format or stated membrane compatibility. The aggregate ratings are mostly five-star, but do not establish how well it will perform on a particular garment.
