I have a Raleigh retro kit knicks & jersey.
Sky official jersey 1/4 zip & orica green edge jersey full zip.
Blitz Jersey first edition - use on sunny days
cheap Craft knicks & red craft jersey
knockoff garmin kit knicks jersey & sleeveless jersey. they were good for one season but are pretty average now and only get used when im at the bottom of the drawer.
also have a black Nalini jersey, which I rarely use as its not very visible on the road, unless im on my yellow road bike.
unless your riding everyday once you have a few sets you really only need to add 1 good jersey/knicks a year. I wouldn't get the cheap knock off stuff again. but would just wait until stuff I like is on sale. wouldn't mind adding a yellow gillet.
