Very good advice from all above. I can bowhunt until mid-January and believe me, in east central Illinois it gets cold. I start off with polypro thermals, then wear the 2 layer thermals over. Next I wear a wool shirt with blue jeans or fleece pants. I wear my Predator Fall Gray thinsulate bibs and a thinsulate jjacket. I never wear the jacket until I get to my stand site and my bibs are unzipped. Sweating in the cold is our enemy. I wear a thick pair of wickable/wool socks followed by 100% wool socks under my 600 gram Wolverines. Finally I wear a warm but not thick glove on my non-shooting hand and my right hand bares only my release but...........those body or hand warmers are a must!!!!
