I wore sponsored jerseys with pride when I raced for sponsored clubs. Since then, I have worn plain jerseys with some exceptions. I prefer bright, usually yellow jerseys (simply because I see so few roadkill yellow squirrels I figure that's the crowd to hang out with) and that often limits the pickings. I now have an LG jersey and a Bianchi jersey in jellow. Sometimes I need a jersey and there aren't many choices. I have a Hincapie Felt jersey because I showed up at a ride and forgot mine. And I wear with pride my 25th year Cycle Oregon jersey. That year I rode the Crater Lake ride fixed. Day four was 98 miles and 9800' of climbing. That started 4 consecutive 5000'+ days. Feel I earned the right to wear that jersey.
