I started using gloves when I began competing, and now I use them all the time, even at home. I use Akers food service synthetic, powder free gloves, six bucks at the local restaurant supply. I even keep a separate box in my home kitchen. Pretty much all the same reasons as posted by others, more sanitary, easy clean up. Keeps hands from getting all smelly too.
