If I didn't like the look/feel of a cycling jersey, I'd wear tech running shirts and get some type of frame bag for storage. That's what I usually do now, anyway. A cycling jersey that fits my upper body/neck is way too long/loose for the lower body. They end up looking like tunics. Standing around, the elastic bottom will gather at the bottom of the glute region. Even the standard AeroTech jerseys do this.
