Wear what you like; I've got a Jelly Belly, Discovery, Euskaltel-Euskadie, plus some plain-Jane jerseys. I think the team jerseys look cool(most of them). I'll be buying some more, no doubt. A 7-Eleven jersey would be cool, some retro Italian ones in merino wool, etc.

voler, pearl izumi, assos, canari, giordana, louis garneau, performance, descente, et al have plain or non-logo jerseys.

Hey, just like Stoler wore in Breaking Away.
