The minimum allowed diameter of a golf ball is 42.67 mm and its mass may not exceed 45.93 g. Modern golf balls have a two-, three-, or four-layer design constructed from various synthetic materials. The surface usually has a pattern of 300-450 dimples designed to improve the ball's aerodynamics by reducing the ball's drag-inducing wake and allowing spin on the ball to create lift. The method of construction and materials used greatly affect the ball's playing characteristics such as distance, trajectory, spin and feel. Harder materials, such as Surlyn, usually result in the ball's traveling longer distances, while softer covers, such as urethane, tend to generate higher spin, more "feel" and greater stopping potential. Golf balls are separated into three groups depending on their construction: two-, three-, or four-piece covers. Generally four-piece golf balls tend to be the most expensive, though price is no assurance of quality.
Many golfers wear special shoes. The shoes can be spikeless or with spikes attached to the soles. The spikes can be made of metal or plastic (plastic spikes are also known as "soft spikes") designed to increase traction thus helping the player to keep his/her balance during the swing, on greens, or in wet conditions. In an attempt to minimize the severity of spike marks made on greens, many golf courses have banned metal spikes, allowing only plastic spikes during play.
It makes it easier to shoot a low score on the golf course when you have the right clubs. They should feel good in your hand, make solid contact with the ball, and be durable enough to last for many seasons. Even if your golf technique is not the best, a quality golf club may help you get more distance and reduce your tendency to hit a slice or draw.
A golfer typically transports golf clubs in a golf bag. Modern golf bags are made of nylon, canvas and/or leather, with plastic or metal reinforcement and framing, but historically bags have been made from other materials. Golf bags have several pockets designed for carrying various equipment and supplies required over the course of a round of golf. Virtually all bags are sectioned off with rigid supports at the top opening, both for rigidity and to separate clubs of various types for easier selection. More expensive bags have sleeves or pockets within the main compartment for each individual club, allowing for the desired club to be more easily removed from the bag and then returned without interference from the grips of the other clubs or internal hardware of the bag.
Most golf bags have a ring to which a player can tie or clip a golf towel, used to wipe hands and clean or dry balls and club faces. Some of these towels can be quite specialized, with a carabiner or other clip to attach it to the bag with a grommet used on the towel for durability, and incorporating rougher materials in certain sections of the towel for club and ball cleaning with softer weaves elsewhere for drying. Other cleaning products abound, from motorized ball cleaners to an array of brushes for various types of clubs as well as balls and shoes.
Golf clothing includes gloves, shoes, and other specialized golf attire. Specialized golf attire (including shirts, pants, and shorts) is designed to be nonrestrictive to a player's range of motion and to keep the player warm or cool and dry while being fashionable, although a common stereotype of amateur golfers is that of wearing clothes that have long been out of fashion (or were never fashionable to begin with), kept in the back of a drawer or closet for the rare occasions the person is able to play a round.
