A neckwarmer is pretty much a winter hat with the top cut off. You could also use a scarff. You could find them in sporting goods stores, maybe with ski stuff.
Good luck archery hunting next year. Im sure you will enjoy it. I also get cold hands and feet. Hardly every while archery hunting, but always while gun hunting. I guess I sweat a little while walking, and get cold while standing still.
