I used this on my Sherpa Vadja insulated jacket. It did improve the water-resistance - for a few weeks. Water doesn't soak through the entire jacket, but it no longer rolls off the outer shell - not even light PNW misting. It's ok, and definitely better than nothing, but when I'm expecting real rain, I wear a rain jacket.
