Staff golf bags
Staff bags are the largest type available, and are commonly used by professional golfers. Most staff bags hold all 14 clubs, with ample room and pockets for additional equipment. They are usually made of leather or other tough materials. They are meant to be carried by caddies rather than the players themselves, as they are heavy and can interfere with the game. They are also called tour bags.
Cart golf bags
Cart bags are slightly smaller than staff bags, but are still too large to carry conveniently during the game. They are designed to be carried on golf carts, and usually have specially placed pockets to make them accessible without removing the bag from the cart. They offer less storage space and fewer pockets than staff bags. They are made from lighter materials, although they are still heavier than carry bags and cannot be carried over long distances.
Carry golf bags
Carry bags or travel bags are small, light bags designed to be carried along the course. They are made of lightweight materials such as nylon and plastic, and usually carry basic equipment including golf balls and a number of clubs. Some also hold complete 14-club sets. They usually come with back or shoulder straps, allowing the user to play without setting the bag down.
Stand golf bags
Stand bags have lightweight legs that prop the bag up when placed on the ground. The legs are usually spring-loaded and retractable, pulling out automatically when the bag is set on the ground. The stand positions the bag at an angle that allows the user to easily reach for clubs during the game.
