I've worn it once so far. I was at the driving range when a rain and wind storm hit. All 40 of us at the range stepped back from the hitting bays to get under cover. I put on my rain gear including my Alvin, Delta Blue, rain jacket and stepped back out on the hitting bay to continue my practice. I hit 112 golf balls over the next hour. The Alvin jacket offered exactly what I want and is exactly as advertised by Galvin Green. It is totally water proof and wind proof. It is light weight and breathable, thus it did not cause me to sweat. It does not restrict my golf swing in any way. The blue color stands out in a good way. I measure 45.5" around the circumference of my chest. The 2XL Alvin fit me perfectly. I am 72" tall and the 2XL Alvin came to the bottom of my hips.
