Full zip jerseys work so well it's a wonder they weren't standard sooner. For today's monthly C&V ride, I wore an old NorCal Forum jersey from 2008, with a half zip. It's not horrible, but it is less convenient. Plus the zipper is one of those sucky Voler ones. It was mild enough today that I could just leave it zipped up.
