I have found that fleece pullovers work really well for wind stopping. I have a pair of bibs and a gander mountain guide series orange jacket for gun hunting. the bibs and the jacket block the wind really nice. i dont know what the bibs are made out of, but they are nothing fancy, just average, run of the mill hunting bibs. but they are pretty well insulated, so that probably goes a long way in the wind blocking. in general though, i have found that fleece works great to help block wind.
