As a long time archery hunter and predator caller I am another that just doesn't believe that some special clothing is necessary to experience close encounters with wild critters. I've had a couple of very close encounters both with a bobcat and a few coyotes while calling and I've had elk and deer both very close and I don't wear any special clothing. The fact is movement is a big killer of close encounters as well as your scent. Don't move and don't let them get down wind and they will get plenty close from time to time.
