Just don't go out in the rain...
Waterproof..... Hmmmm.... Wish I could say it soaked through while sitting out a storm in the tetons.... Or blizzard conditions in Mammoth... A down pour while hiking in King's Canyon. But no, mine soaked through when I got caught in the rain.... at Disneyland. Really. Arms from the forearm down were soaked. Shirt underneath starting to wick and soak. Phone in my jacket pocket... soaked. Wow. In a moderate southern california rain storm. I am disappointed to say the least. The good news is my girlfriend was wearing the marmot rain shell and was dry as can be. But this jacket gets relegated to the "wear when walking the dog when there's a slight chill out" pile because it does not handle real weather (or moderate rain for that matter). Just glad I found this out before taking it into a situation where staying dry REALLY mattered.
