Randy Wwrote a review of Gore Bike Wear Xenon 2.0 SO Jersey - Long-Sleeve - Men's on December 1, 2017
Medium fits perfectly. The mesh-lined zips on the sleeves are great once you've warmed up. The neck is really high--especially in the front, which I like, and the back is nice and long and doesn't creep. Deep rear pockets good for large phones like iPhone Pluses.
