I have always wondered this. Most golfers do not put covers on their irons, myself included. Why do most golfers, myself included, keep a head cover on our drivers and woods. What about our woods and drivers make them require protection? I know they tend to be hollow and dentable, but 20 years ago they were solid wood and most people kept them covered. I have seen threads here discussing if you should have your irons covered but why should I have my woods and driver covered?
