I can't recommend a specific brand (I have some Cannondale tights I love, but found them on the clearance rack at Performance and have no idea of the make/model), but I do recommend going with the no-chamois tights. Reason being, if you wear them over your bike shorts, you don't have to wash them every single time you wear them, so they'll last much longer (and be available the next day if you do back-to-back chilly rides!) As offthegrid suggests, you can also use them for walking or running without bike shorts underneath (I did that tonight on a run, actually!)

Another plus: the double layer of fabric on your quads keeps your muscles warmer than tights alone.

And one more: if you get tights with ankle zippers, you can easily peel them off at a rest stop if it gets too warm for them. Try doing that with tights w/chamois!

Hope you find something nice!
