The Evolution of the Football Helmet

From bare heads and leather caps to certified plastic shells with padding and face guards, here is how the football helmet developed and what it can and cannot do.

Look at a photograph of an early football team and one thing stands out: most of the players have nothing on their heads but their hair. It is easy to assume that helmets were always part of the sport. They were not, and the story of how they arrived is really the story of the game changing around the people who played it.

The modern helmet is a layered piece of engineered equipment: a hard outer shell, internal padding, a chin strap and a face guard, all built to a testing standard. It took roughly a century to get there, and the progress came in fits and starts, usually after an injury problem forced somebody to act. Along the way the helmet also became a billboard, a communications device and a symbol of the sport.

This article follows the helmet from its earliest forms to its present shape, explains the testing standards behind it, and describes what a helmet can reasonably be expected to do. It is not medical advice. For decisions about a specific player or injury, talk to a doctor or an athletic trainer, and follow the rules of your league.

When nobody wore one

Football began as a rough game. Early versions, borrowed from rugby and soccer, were played with little equipment, and the most common form of protection was a mass of long hair. Players did sometimes wear padding on their shoulders or legs. Headgear was a different matter, and it was slow to catch on. Many players considered a helmet unnecessary or even unmanly, and coaches had little reason to insist.

That began to shift as the game grew more violent. The early game relied on mass formations that sent groups of players crashing together, and injuries were frequent and sometimes fatal. Those years led to major rule changes that you can read about in The 1905 Crisis and the Birth of the NCAA. Protective gear was one response, though it was uneven and optional for a long time.

Leather and the first protective caps

A story widely repeated in football history holds that the first helmet-like device was made for a Navy midshipman named Joseph Reeves, who played in the Army-Navy game of 1893. According to that account, a doctor warned Reeves that another blow to the head might put him in serious danger, and a shoemaker fashioned a leather covering for him to wear. Retellings differ on the details, so treat the story as the commonly told version rather than a settled fact.

What is clear is that the earliest headgear was made of leather and was meant to cover the ears and the top of the head. Players sometimes called these early pieces head harnesses or head protectors. A typical one was a leather cap with ear flaps, and some versions added straps across the crown. They offered limited protection against impact but could shield a player from scrapes, cuts and the damage that came from having the ears hit repeatedly.

Through the first decades of the twentieth century, leather helmets slowly became more common, but they remained optional. In some seasons, many players on a team wore them and a few did not. Because there was no common standard, one player's "helmet" might be thick and well padded, and another's might be little more than a cap.

Plastic shells and the first mandates

The big technical leap came with plastics. In the late 1930s, the Riddell company, which had been founded by John T. Riddell in the 1920s, introduced a helmet with a molded plastic shell. A plastic shell could be made to a consistent shape and could spread the force of an impact over a larger area than soft leather could. It was also more durable, so it protected the player across a whole season.

Supply constraints during World War II slowed the spread of plastic, but the trend was set. Professional football began to require helmets in the early 1940s. By most accounts, the last NFL player to take the field without a helmet was Dick Plasman, who played in that period, though sources differ slightly on exactly when. In the years after the war, the NFL moved to require hard plastic helmets, and by around 1950 the old leather helmets were gone from the pro game.

The dates in the middle of the table are approximate, and some of them differ by a year or two depending on the source. If you need a specific year for a specific rule, check the league's own history.

The face mask

Plastic shells protected the skull, but faces remained exposed. Broken noses, jaw injuries and facial cuts were everyday risks. The earliest solution was a face guard, a bar of plastic or metal that attached to the front of the helmet.

A widely told story credits the Cleveland Browns and their coach, Paul Brown, with an early face guard in the early 1950s, after quarterback Otto Graham was hurt by a blow to the face. The story is often repeated, though the details vary from telling to telling, so take it as the traditional account. What matters is that the idea spread. Through the 1950s and 1960s, face guards became standard, and they gradually grew from a single bar into more elaborate cages.

Face masks changed the game in a way their inventors might not have intended. Once players could not be hurt as easily in the face, they could lower their heads to tackle and block with less fear. That change in behavior contributed to a new class of injuries involving the neck and head, which later led to rules about the way the head can be used. College football banned spearing, the practice of using the top of the helmet as a weapon, in the 1970s. Tackling technique, and the rules that govern it, have continued to evolve since. For the rule changes that followed, read A Century of Safety Rules in Football.

Face masks also introduced a penalty that is still enforced: grabbing and twisting an opponent's mask is a foul at every level. Our explainer on face mask penalties covers the details.

Why standards finally arrived

By the late 1960s, helmets had improved, but there was no consistent way to know whether a helmet was good. A manufacturer could claim protection without proving it, and schools had few ways to compare products.

In 1969, a group of sports-equipment stakeholders formed the National Operating Committee on Standards for Athletic Equipment (NOCSAE). The group set out to create testing methods for athletic equipment, and its first football helmet standard followed in the early 1970s. A helmet that passed the test would carry a NOCSAE certification, and a helmet that did not pass could be rejected.

Adoption followed in stages. The standard became a requirement at the college level and then in high school, in the late 1970s and early 1980s. The exact years are worth verifying if you need them, but the effect was straightforward: schools could no longer buy an uncertified helmet and put it on the field. Today, NOCSAE-certified helmets are the baseline for high school and college football in the United States, and helmets carry labels with warnings and certification marks.

Certification means a helmet passed a laboratory test. It does not mean a helmet will prevent every injury, and it does not make one certified model the same as another in how it performs. Those gaps are why more testing and ratings programs appeared later.

Padding, air and a new generation of shells

Inside the shell, the padding matters as much as the plastic does. Early plastic helmets used felt or simple foam. Over the following decades manufacturers experimented with several approaches, including:

• Foam liners of different densities, stacked and shaped to absorb energy.
• Air-filled cells in the padding, which can be inflated to fit the head more snugly.
• Liquid-filled and gel-filled designs, intended to spread the force of a blow.
• Suspension systems that hold the head away from the shell.
• Flexible and layered outer shells, introduced in the 2010s, that are designed to deform slightly on impact.

None of these approaches is a miracle, and no single design has proved the best at everything. A foam that works well against one kind of impact may perform differently against another, which is why engineers test helmets with many different impact speeds and locations.

Independent researchers also began rating helmets in the 2010s. A well-known program at Virginia Tech started publishing ratings of helmet models in 2011, using laboratory testing to score how well each model reduced a measured risk of concussion. The NFL and the NFL Players Association (NFLPA) have conducted their own laboratory testing and have shared which helmet models perform best and worst, and they have told players that some older models are no longer acceptable for use. Because these programs update their results, you should look at the most recent versions rather than trusting old rankings.

More recently, padded covers that fit over the outside of a helmet have been used in practices. The NFL has required them for some positions in training-camp practices since the early 2020s, aiming to reduce the force of the many small hits that happen during practice. Whether they reduce injuries as much as hoped is a subject of ongoing research, so we do not make claims about their results.

What a helmet can and cannot do

This is the point where honesty is most important. A modern helmet is very good at one job: reducing the risk of severe injuries such as skull fractures and bleeding in the head. The certification test was designed around that goal. A helmet is less capable of preventing a concussion, which can result from the brain moving inside the skull even when the head is well protected from the outside.

That is why every helmet carries a warning, and why leagues and doctors emphasize technique and rules in addition to equipment. A player who uses poor tackling technique, even in a top-rated helmet, is still at risk. The best protection combines gear that is well fitted and well maintained with correct technique, enforced rules and attentive medical staff.

If you are a parent, a coach or a player, here are general points that most safety organizations stress:

1. Fit matters. A helmet that is loose, tilted or the wrong size does not protect as designed. A trained equipment manager or athletic trainer should fit it. If you are looking for a recreational league, our Play section is a place to start, and any league you join should be able to tell you its equipment rules.
2. Condition matters. Cracked shells, worn padding and broken straps need to be fixed or replaced. Many programs have helmets inspected and reconditioned on a schedule.
3. Do not modify it. Drilling, repainting with the wrong materials or adding stickers can interfere with the helmet's performance and may void its certification.
4. Technique matters. Keep the head up when you tackle and block, and avoid using the helmet as a weapon.
5. Report symptoms. Any player who may have a head injury should be evaluated by a qualified medical professional before returning to play. For how the pro league handles this, read The NFL Concussion Protocol Explained.

None of this replaces advice from a physician, and the rules for your league or state take precedence. For information about the injury report in the pro game, our injuries page tracks reported statuses.

Helmets as communication and identity

The helmet has also taken on roles that have nothing to do with safety.

Logos and colors. For many years helmets were plain. In 1948, the Los Angeles Rams became the first NFL team to put a design on their helmets, with a player named Fred Gehrke painting horns on them by hand. The idea caught on across the league, and today helmets are one of the most recognizable pieces of a team's identity. Our teams page shows each club's colors and branding.

Radios. In 1994 the NFL began allowing a small receiver in the helmet of one offensive player, the quarterback, so a coach could send plays in from the sideline. A green dot on the back of the helmet marks the player who has a working receiver. The league later extended the idea to a defensive player as well. Those details can change, so confirm them in the current rulebook. The college and high school levels have their own rules about electronic communication.

Visors. Tinted or clear visors are another accessory, with specific rules about what is allowed.

Common myths

• "Leather helmets were safer because players were afraid to hit with their heads." This is a popular idea, but there is no simple evidence for it. Early helmets protected little, and the injuries of that era were severe.
• "A bigger helmet is a safer helmet." Not necessarily. Fit and padding matter more than size.
• "If it is certified, it cannot fail." Certification means it passed a defined test, not that it prevents every injury.
• "Soft covers make a helmet concussion-proof." No evidence supports that claim, and researchers continue to study them.
• "Every helmet is basically the same." Testing shows meaningful differences between models, which is why ratings exist.

The short version

• Early football players mostly went without helmets; leather caps came into use around the turn of the twentieth century and stayed optional for decades.
• Plastic shells arrived in the late 1930s, and the NFL required helmets in the early 1940s and hard plastic by about 1950.
• Face guards spread in the 1950s and 1960s, which protected faces but contributed to riskier use of the head and eventually to rules like the spearing ban.
• NOCSAE formed in 1969 and issued the first helmet standard in the early 1970s, making certification the baseline for high school and college.
• Modern helmets reduce severe head injuries, but no helmet makes a player concussion-proof, so technique, rules and medical care remain essential.
• Helmets also carry logos, radios and other features that have little to do with safety.
• For decisions about a specific injury or equipment issue, ask a doctor, athletic trainer or your league.
