Protective equipment in gridiron football ("football gear") consists of equipment worn by football players for the protection of the body during the course of a football game. Basic equipment is worn by some football players including helmet, shoulder pads, gloves, shoes, and thigh and knee pads. Neck rolls, elbow pads, mouth guards, hip pads, tailbone pads, rib pads, and other equipment may be worn in addition to the aforementioned basics. Football protective equipment is made of synthetic materials: foam rubbers, elastics, and durable, shock-resistant, molded plastic. Football protective equipment has remained consistent in use for decades with some slight modifications made over the years in design and materials. The assignment and maintenance of football gear belongs to the team equipment manager.

The professional football helmet consists of several distinct parts: the sheep, jaw pads and abdomen bladders, face mask, chin strap, and mouth guard. The shell is constructed of hard plastic with thick padding on the inside, a face mask made of one or more metal bars, and a chinstrap used to secure the helmet. Helmets are a requirement at all levels of organized football, except for non-tackle variations such as flag football. Although they are protective, players can and do still suffer head injuries such as concussion.
Each position has a different type of face mask to balance protection and visibility. There are at least 15 different facemask styles. New design for the helmet includes an integrated faceguard featuring shock absorbing "Energy Wedges" that reduce the force of impacts to the faceguard.
The NFL allowed dummy communication in regular-season games in 1994. Rather than coaches calling a time-out in order to give a play to a quarterback, many of today's teams are opting for radios inside their quarterback's helmet. The helmets are set up with a small speaker in each ear hole. Quarterback coaches or offensive coordinators on the sidelines talk to the quarterback with a radio, giving him specific plays and options. Players from the "old school" might argue that this creates an unfair advantage, but proponents say that the radio helmets make for clear coach-to people communication, even in large, noisy games like the Super Bowl.
NFL rules state that all helmets with a headset in them must have a visible green dot on the back. Since only the quarterback can have a wired helmet, it stops other players using the quarterback's helmet. A few times in 2006 the holder on the field goal attempt was told to pull up and throw or run at the last second because of a change the coaches saw on the field. This gave teams an "unfair advantage" in the eyes of the NFL. The new rules let each team know who is wearing a headset and who is hearing the plays being called.
According to a press interview held with the Tampa Bay Buccaneers, the quality of the sound is good, but crowd noise factors in. “It’s about like what you’d hear over a loudspeaker,” said Bucs QB Shaun King. “It can be hard to hear when there’s a lot of noise on the outside, but it’s pretty cool."
A more recent addition to the football helmet is a visor or eyeshield, traditionally used to protect players from eye injuries or glare. Former Chicago Bears quarterback Jim McMahon was the first to wear a visor/shield. The visors started out as clear or smoked, but now come in colours ranging from blue, gold, black, rainbow, silver, or amber. The visor/shield is used at the player's discretion.
The helmet fitting process starts by measuring the player's head with calipers. Based on measurements taken, a helmet shell of the appropriate size and style is chosen Then, padding is added to ensure that the helmet fits the player's head. Padding consists of both foam rubber pads and inflatable (air) pads. Both the top and side padding include inflatable bladders that customize the fit. Once the helmet is in place on the player's head, the inflator bulb is applied to two points on the outside of the helmet. The jaw pads are fitted to ensure that the lower part of the helmet is snug against the player's face. The helmets that most NFL teams use are remarkably light, and once the pads are in place, there is no movement or shifting on the player's head.
Football helmets are painted in team colours and bear team insignia decals.
There are several styles of face masks and chin straps available. The selection is left to the player, with quarterbacks generally selecting more open masks with maximum visibility.
Off the gridiron, football helmets figure in the masculine decorative schemes seen in home dens, bars, and rec rooms, for example. Antique and vintage leather football helmets are collectibles and most are really expensive.
Shoulder pads 
The shoulder pads consist of a hard plastic outer shell with shock-absorbing foam padding underneath. The pads fit over the shoulders and the chest and rib area, and are secured with various snaps and buckles. Shoulder pads give football players their typical "broad-shouldered" look, and are fitted to an adult player by measuring across the player's back from shoulder blade to shoulder blade with a soft cloth measuring tape and then adding 1/2 inch. For comfort, shoulder pads are sometimes worn in conjunction with a shoulder pads cushion of foam rubber over a cotton half-tee.
Shoulder pads accomplish two things for a football player: (1) they absorb some of the shock of impact through deformation. The pads at the shoulders are strung on tight webbing and deform on impact, and (2) they distribute the shock through a larger pads that is designed to regulate players' body temperatures during games and practices.
Jockstrap, or athletic supporter 
A typical jockstrap used in football is constructed of a wide elastic waistband with a support pouch of cotton/elastic to contain the genitals. Two wide elastic straps affixed to the base of the pouch and to the left and right sides of the waistband at the hip complete the jock. The pouch, in some varieties, may be fitted with a pocket to hold an impact resistant cup to protect the testicles and penis from injury. Pop Warner (youth football) players may be required to wear a protective cup. However, they are not worn as often, at the high school, college, and peewee level, although it is still highly recommended. The jockstrap is the one piece of equipment used in football that predates the sport itself. In 1874, Charles Bennett of the Chicago sporting goods company, Sharp & Smith, created the "bicycle jockey strap" for bicycle riders (or, bicycle jockeys as they were then known). Other athletes adopted the jockey strap in their sports. A mass marketing in 1902 claimed the garment, now termed an "small comforter" was "medically installed" for all males that engaged in sports or harmful activity.
Jerseys and pants 
The main purpose of these two garments is to identify the player by name and number, and by his team colours.
Jerseys. The front and back of the jersey are usually nylon, with spandex side panels to keep it taut. The goal is to make it difficult for an opposing player to grab hold of the jersey and use it for leverage. To help this process: Jerseys have an extension at the bottom that wraps around from front to back to keep the jersey tucked in. Jerseys have a wide strip of Velcro at the rear that mates with Velcro inside the waistband of the pants. Many players apply two-sided carpet tape to their shoulder pads so that the jersey sticks to the pads. The players individually choose which of these features (if any) they will use. Each professional football player is usually equipped with a set of practice jerseys as well as four game jerseys. Players will change jerseys at half time if it is raining. Jerseys will usually have a variety of patches affixed to the shoulders or other parts of the garment. Patches may depict the American flag, the team logo, or other significant information.
Pants. Pants are manufactured in nylon and mesh (for hot weather practices), and nylon and spandex for a tight fit (with team colours) for games. Most pants are manufactured with the traditional lace-up fly as a zippered fly is impractical and subject to damage due to stress in the rough and tumble of the game. The interior sides of the pants legs contain four individual pockets to hold two thigh pads (one for each leg) and two knee pads. The pads are placed in the pockets before the pants are put on in the locker room. The pants are secured with a belt, sometimes with a traditional metal buckle or with several rings. Game-used jerseys and pants are sports collectibles, with those of celebrity athletes realizing high sums.
Spiked shoes called "cleats" are worn on grass, with removable, screw on cleats. Cleat sizes are changed, depending on the condition of the field (longer cleats give better traction on a wet field, shorter cleats give greater speed on a dry field). Flat bottomed shoes, called "turf shoes," are worn on astro-turf.
Hip, tail, thigh, and knee pads 
Quilted hip pads date to the 1890s and are one of the earliest pieces of protective football gear known. Today, hip and tailbone pads are made of plastic and protect the hips, pelvis, and coccyx or tailbone. The pads are inserted into the pockets of a girdle worn under the football pants. Thigh and knee pads are made of plastics and inserted into pockets constructed inside the football pants.
Mouth guard 
Sports mouthguards (also termed athletic mouthpieces) are plastic dental appliances which can help to protect the hard and soft tissues of the mouth from damage caused by traumatic blows and collisions. They are also designed to absorb the shock of impact to the head reducing the incidence of concussions (although the typical boil-and-bite mouthguards may not be very effective at this). Mouth guards are simple half-moons of plastic with a strap on the end which hooks around the face mask so it isn't lost during play. Fitting a mouth guard is simple: it is placed in boiling water, allowing the plastic to soften. It is removed from the boiling water, and then placed for a second in cold water. The cold water dip cools the exterior of the plastic (so that it won't burn the mouth), while leaving the interior of the plastic soft (so that it can be formed). Then the player puts the mouth piece in his mouth and bites down, leaving an imprint of his teeth and gums. As the plastic cools, the mold hardens. The result is a mouth guard specific to one player's mouth.
Many receivers wear gloves that either have a sticky rubber palm, called tact gloves. Spray on sticky substances (such as Stick 'em) have been illegal since the 1980s. Linemen also wear gloves, for using their hands to fight off opposing linemen. The gloves worn by linemen usually are lined with very thick padding to better protect fingers and hands, which sometimes are caught in an opponent's face mask or are stepped on. Players are not permitted to put gels or "stick 'ems" on their gloves.
Equipment management 
The role of an equipment manager has become an important one for football teams. The equipment manager has two main areas of responsibility: first, fitting each player on the team with a customized array of equipment that will provide maximum protection against injury, and, secondly, being responsible for the logistics of handling many pieces of equipment on a daily basis—keeping it repaired and in stock, and moving the equipment for road games.
