Yeah, I wear one pretty much all of the time. The reason is this... I never seem to shoot from the same place, height, or angle twice when I'm walking through the woods. Sometimes I have to adjust my stance and how I am holding the bow just to get around branches and what not. So, most of the time I don't have a problem slappin my arm but on those few occasions when it does whack it good, I'm glad I have the gaurd. If you are getting hot wearing one, try one of the skeletal types that just have three lengths of plastic and are open. They are a lot cooler on hot days.
