The most recent was not so recent. In 2006 my eVent rain jacket wetted out at the shoulders but didn’t penetrate. This can still make it colder in that area. I tried Nikwax TX Direct and followed instructions but it didn’t work for that jacket, nothing changed.

Previously I tried to give an older Houdini a DWR refresh but don’t remember the brand. It was a spray bottle and whatever it was didn’t make much difference at all.

Perhaps in the ensuing decade and a half things have improved but I’ve never tried it again.

Sctch guard works well for my Tilley hat if applied regularly. Never tried it on a jacket
