These don't have the windblocking feature, but what about the Pearl Izumi Thermal tights? I have a pair of the Elite and the Select series. I live where it's windy all the time, and I find the PI tights to be just fine in temps between 35-50. On the colder days (30's), I tend to go with the thicker Elite's, but on milder days (40's) the Select's work fabulous.
