I wear my club (and team) kit almost exclusively on the road. It advertises the club, looks smart, and the white long sleeved summer jersey protects me from the sun.
As mentioned, no leaders jerseys, but riding in a supporters kit says you support a team in some way. I rather like the OPQS kit and like Michal. Also team kit is normally very well made. The Champion Systems club kit we wear is the same as Lampre.
When racing off-road, I still wear my club kit – and we are a road club. It’s just to get the club noticed and “out there”.
One day i’ll have that Master’s Jersey.
