Staff bags are big enough to hold everything a pro would need. In fact, they are usually designed after the custom golf bags pros use, so they are larger and heavier than regular golf stand bags. Staff bags are often made of leather and have large pockets. They have space for a full set of 14 golf clubs.
It is common for experienced caddies to carry two bags at a time. It is considered acceptable to ask a professional at the course what the average pay for a caddie is, as courses differ. In a professional golf tour setting, a player often pays their caddy a percentage of their winnings, which can be as high as 10%. A common pay scale is 5% for making the cut, 7% for a top 10, and 10% for a win. The caddy also usually receives a salary, as the player is not guaranteed to win money at every tournament.
