I recently bought a Gore bikewear ShakeDry jacket. I brought it along on a few rides when it was forecast to rain, but it didn't rain. I gave credit to Gore for keeping me dry. e A couple days ago it started raining just as I left the house, and it rained the entire ride, a quick 20 miler. I had an Assos Spring/Fall long sleeve jersey on under the ShakeDry jacket, and I was dry inside that jacket at the end of the ride. My PI booties soaked through, my Assos rain hat kept my head dry, and I was impressed beyond belief at the performance of that ShakeDry! I fully expected to be sweaty and soaked inside, especially as hard as it rained at some points, but I was dry. Even the neck didn't leak. I was skeptical. I own, and have owned, tons of GoreTex and similar products from other manufacturers over the years. I expected the same old result from the ShakeDry jacket, but I was elated to find out that it worked better than I could have hoped. I'm sold.
