I have plenty of jersies but they are all race fit and race "looking" from Pearl Izumi, Craft, etc. Today I wore a Rapha Club jersey on a singlespeed ride (casual, not a race) and it was fun. It was nice not to have something so tight one and it looked casual too, like I wasn't out there trying to go fast, but just riding my bike. I like that it still wicks moisture and still utilizes a "technical" fabric.
With that said, besides Rapha, who else makes fun club fit jersies? I read that PI makes some but they all look "race-y" to me.
