I've worn an Evening Stand Green pullover quite a bit the last two seasons with good results (for example, I had a group of 5 does + yearlings bust me crossing a road recently at about 50 yards; I froze, they looked me up and down and kept on walking while I continued my mime impression of 'Dumb Hunter Crossing Road in Freezing Cold'). I've also worn a number of solids too though with similar results; I think it has more to do with me wearing wool almost all the time nowadays, I really think it helps a lot with blending into various lighting conditions where synthetics can tend to stand out.
