I'm actually wearing a pair RIGHT NOW (our building's heat hasn't turned on yet). The windproofedness does not impress me, but they're a decent base layer IMO. I'll wear them down to 50° on their own or under BDUs, but otherwise I wear Pearl Izumi's AmFib winter tights down to 40°, then the AmFib tights over the Under Armours down to 20° with a pair of wool legwarmers thrown into the mix on the lower end.
Below 20° I wear three pairs of tights and a large pair of brass spheres in the crotchal area.
