Houdini equivalent in pants?

I'm in love w/ my Houdini "wind" shirt- very light, packs to next to nothing, stops the wind and I've found it to be very good in short or lighter rain events (if it does wet out, it dries fast)

I'm looking for an equivalent now in pants. These would be most often layered over shorts, but if cold enough- over some light fleece ( R1) pants

thanks in advance

Mike
