Player equipment and it's use

I was watching a Tigers game the other night (big surprise there right?) and noticed Miguel Cabrera was wearing a batting glove under his first basemen mitt and got me wondering how long do they wear any given equipment? Well I did a little research and the results are a little... Now keep in mind most of these guys are millionaires and this would include spring training.
