Lacrosse is a sport that has been played for centuries by indigenous people in North America, and it has recently gained popularity in the modern world. One of the most important components of the game is the lacrosse ball, which is used to score goals and advance the ball down the field. But what are lacrosse balls made of? 


In this article, we will explore the materials and manufacturing process used to create these small but mighty balls that are essential to the game of lacrosse. From rubber and plastic to cork and leather, we will take a closer look at the different materials that go into creating a lacrosse ball. 


Additionally, we will also discuss the importance of ball size, weight, and bounce in relation to the sport, and how different materials impact these factors. So whether you’re a seasoned lacrosse player or simply curious about the sport, read on to learn more about what makes a lacrosse ball tick.


What Are The Modern Lacrosse Balls Made Of?

Lacrosse balls must be constructed of a solid, elastomeric material to meet certification requirements. Manufacturers of lacrosse balls have access to a wide range of elastomeric materials, including silicone, polyurethane, latex rubber, and several kinds of vinyl.


There are currently two varieties of lacrosse balls approved for use in competitions:


  • Latex Rubber balls made overseas


Lacrosse balls for the vast majority of brands are produced by two or three factories in China and Taiwan. The private-label balls for these brands are produced on the same production lines and with the same formula by these producers. They use vulcanized latex rubber, a process used to create automobile tires and footwear that combines natural rubber with various oils, fillers, and additives.


Rubber lacrosse balls are firm and sturdy but when these oils and fillers seep out of the rubber balls, they become greasers and are slippery. As with car tires, with repeated exposure to the outdoors, the rubber degrades and hardens.


  • Crosslinked Polyurethane (patented) balls made in the USA


The crosslinked polyurethane compound used to create PEARL X and NX lacrosse balls is produced in the USA. The mixture doesn’t contain any oils, fillers, or Prop 65-prohibited materials, therefore it is never greasy or gets hard. The Guardian Sports chemists who developed the lacrosse ball recipe desired a ball that maintained its specifications and did not lubricate. A comparable material called polyurethane is used to create common household goods and agricultural equipment that has received FDA approval.


What Were Lacrosse Balls Made Of In The Early Days?

The modern lacrosse ball is composed of solid rubber, while lacrosse balls have historically been constructed of a variety of materials. Lacrosse balls are made by many lacrosse manufacturers using a variety of different formulae. Despite these variations, a licensed lacrosse ball must be used in every lacrosse game.


Early lacrosse balls were crafted from buckskin, wood, and occasionally rocks. The existence of these lacrosse balls in nature preserved the game’s connection to the natural world. Lacrosse balls did not become more consistent until Dr. William George Beers codified the game’s regulations in the 1860s.


What Is Inside A Lacrosse Ball?

Do lacrosse balls include cement, you may have heard someone ask? and believed it to sound odd. Well, there was once cement in the middle of some lacrosse balls. Most of these lacrosse balls are no longer in use because this age has passed. None of these lacrosse balls with cement inside of them are allowed to be used during games.


Even after being chopped in half, a lacrosse ball reveals that its interior and exterior are nearly identical. Each authorized lacrosse ball has a circumference of 7.75 to 8.0 inches and is made of a substance that is probably vulcanized rubber.


What Are The Regulations On Lacrosse Ball Size And Weight?

In lacrosse, there are different regulations for ball size and weight depending on the level of play.


At the collegiate and professional level, the ball must be between 7.75 and 8 inches in circumference and weigh between 5.5 and 5.75 ounces.


At the high school and youth level, the ball must be between 7.5 and 8 inches in circumference and weigh between 5 and 5.25 ounces.


In women’s lacrosse, the ball must be between 7 and 7.25 inches in circumference and weigh between 4 and 4.25 ounces.


These regulations ensure that the ball is of a consistent size and weight across all levels of play, allowing players to accurately and consistently throw, catch, and shoot the ball. It also helps to ensure the safety of players, as a lighter and smaller ball may be less likely to cause injury.



In conclusion, the lacrosse ball is a vital component of the game of lacrosse. It is made of a hard rubber material and has a specific size and weight that is regulated by the governing bodies of the sport. The ball is used to score goals by shooting it into the opponent’s net and is also used to advance the ball up the field by passing it to teammates. The lacrosse ball can be challenging to handle and control due to its size and hard surface, but it is an essential part of the fast-paced and exciting nature of lacrosse. Overall, the lacrosse ball plays a crucial role in the game of lacrosse and is a key factor in determining the outcome of a match.
