NFL helmets are made from a combination of carefully selected materials that ensure safety, durability, and performance. Each part of the helmet has a specific role in protecting players from the high-impact collisions that occur during games. Here’s a closer look at the key materials used in different parts of the helmet.
Outer Shell
The outer shell of NFL helmets is primarily made of polycarbonate, a high-impact, lightweight plastic. Polycarbonate is known for its ability to withstand significant force without cracking, making it ideal for absorbing the direct hits players endure. Its durability ensures that the helmet can last through multiple impacts, while its lightweight nature helps reduce strain on the player’s neck during play. The shell is designed to distribute impact forces over a larger area, minimizing the risk of injury.
Benefits of polycarbonate :
Impact resistance : Protects the head from blunt forces.
Durability : Withstands multiple hits without cracking or breaking.
Weight reduction : Keeps the helmet light, ensuring player comfort.
Inner Padding
Inside the helmet, foam padding plays a vital role in absorbing shocks and cushioning the player’s head. The padding is typically made from materials like vinyl nitrile or EVA foam, which are chosen for their ability to compress under pressure and rebound quickly. This padding not only softens the blow from impacts but also ensures a snug fit around the player’s head, reducing movement within the helmet during play.
Functions of foam padding :
Shock absorption : Cushions the head from high-impact collisions.
Comfort : Provides a custom fit to the player’s head shape.
Stability : Prevents excessive movement of the head inside the helmet.

The face mask is a critical component of the helmet, providing protection for the face while maintaining visibility. It is usually made from stainless steel or titanium, materials known for their strength and light weight. Stainless steel is more common due to its affordability, while titanium offers the same strength at a lighter weight, making it a premium choice. The face mask is designed to absorb impacts without bending or breaking, ensuring player safety.
Why stainless steel and titanium are used :
Strength : Provides strong facial protection against impacts.
Lightweight : Minimizes added weight to the helmet.
Flexibility : Offers some give without breaking, reducing facial injuries.
Chin Strap
The chin strap ensures that the helmet stays securely in place during fast-paced action. It is typically made from durable synthetic materials like polypropylene, which are resistant to wear and tear. The chin strap helps keep the helmet snug on the player’s head, reducing the chance of it coming loose during a play. A securely fastened helmet is essential for proper protection.
Key features of the chin strap :
Durability : Withstands repeated use without losing strength.
Security : Keeps the helmet firmly in place, preventing shifting.
Comfort : Designed to fit comfortably under the chin without irritation.
Optional Visor
Some players opt to add a visor to their helmets for additional eye protection. Like the outer shell, the visor is typically made of polycarbonate. Visors can be either clear or tinted, depending on player preference. They protect the eyes from debris, bright sunlight, and even potential impacts, while still allowing for clear vision on the field.
Benefits of polycarbonate visors :
Eye protection : Shields eyes from debris, sunlight, and impact.
Durability : Resistant to scratches and shattering.
Visibility : Maintains clarity while protecting the player’s vision.
These materials all work together to create a helmet that maximizes player safety and comfort while maintaining the performance needed for high-level play. Understanding what NFL helmets are made of highlights the thought and engineering behind protecting players in one of the world’s most physically demanding sports.

Polycarbonate : The Ultimate Choice for NFL Helmet Protection
When it comes to modern NFL helmets, polycarbonate stands out as the material of choice for the outer shell. Understanding what NFL helmets are made of requires a closer look at why this material is favored over others. Polycarbonate is a type of thermoplastic known for its unique combination of properties that make it ideal for high-impact sports like football.
Lightweight and Durable
One of the key reasons polycarbonate is used in NFL helmets is its exceptional strength-to-weight ratio. Despite being lightweight, polycarbonate is extremely strong, allowing it to absorb and dissipate the energy from hard hits while minimizing additional weight on the player’s head. This balance between protection and comfort is critical in football, where heavy helmets could cause neck strain and fatigue.
Lightweight : Reduces the burden on players’ necks, improving comfort and reducing fatigue during long games.
Durable : Withstands repeated impacts without cracking or degrading over time.
Impact Resistance
Polycarbonate is highly impact-resistant, which means it can absorb the force from collisions without breaking or shattering. This makes it ideal for NFL helmets, where players experience frequent and powerful impacts during play. The material’s ability to distribute force across the helmet surface helps to reduce the severity of direct blows to the head, lowering the risk of injury.
Impact resistance : Capable of handling strong impacts without fracturing.
Force distribution : Helps spread the impact energy across the helmet, minimizing concentrated stress on any one point.
Comparison to Older Helmet Materials
Before polycarbonate became the standard, NFL helmets were often made from materials like leather or fiberglass, both of which had limitations. Leather helmets, used in the early days of football, offered minimal protection and did little to absorb the impact of hits. Fiberglass, which replaced leather, provided more protection but was heavier and more prone to cracking upon impact.
Polycarbonate represents a major advancement over these older materials. Unlike leather, which lacked durability, or fiberglass, which was brittle, polycarbonate combines strength, flexibility, and lightness. This allows modern helmets to offer superior protection while remaining lightweight enough for players to move freely on the field.
Leather : Outdated and offered very limited protection.
Fiberglass : Heavier and prone to cracking upon impact.
Polycarbonate : Provides the best of both worlds—lightweight, flexible, and highly durable.
Why Polycarbonate is the Standard Today
Today, polycarbonate is the industry standard in NFL helmets because it meets all the key requirements for player safety, comfort, and performance. Its ability to handle high-impact forces, coupled with its lightweight properties, ensures that players are well-protected without sacrificing mobility.
By comparing it to older materials, it's clear why polycarbonate is now the preferred choice. It strikes the right balance between strength and flexibility, making it the most effective material for protecting players in one of the most physically demanding sports.
