Let's see now. I've got:

2 long-sleeved and 1 short-sleeved Coolmax shirts; not actually cycle jerseys, but close-fitting wicking fabric so near enough.

1 Jaggad short-sleeved jersey, which I don't much care for.

And just today, my Where The Wild Things Are jersey arrived from PrimalWear

When I'm commuting, I just tend to wear Bonds t-shirts; I'm not on the bike for long enough to worry about high-tech fabrics and aerodynamics.
