Sunday bags are commonly advertised as "minimalist" carry bags; they have very light weight and flexible construction allowing the bag to be rolled up or folded for storage without clubs, and have storage pockets for the essentials of play (clubs, balls, tees) but often lack more advanced features like segregated club storage, insulated pockets for drinks, stand legs etc.
Alternately, the rules allow for a mound of sand to be used for the same function, also only on the first shot. Before the invention of the wooden spike tee, this was the only accepted method of lifting the ball for the initial shot. This is rarely done in modern times, as a tee is easier to place, hit from, and recover, but some courses prohibit the use of tees either for traditional reasons, or because a swing that hits the tee will drive it into or rip it out of the ground, resulting in damage to the turf of the tee-box. Tees also create litter if discarded incorrectly when broken.
