SPARKS, Md. — US Lacrosse has renewed a partnership with Guardian to remain the “Official Ball” of US Lacrosse and the U.S. National Teams. This multi-year agreement designates Guardian as an official partner of US Lacrosse and a supporting partner of the U.S. National Teams.

“Guardian has been a great partner that provides a best-in-class product for the sport and continuously strives to bring new ideas to the market,” said Brett Hurwitz, vice president of marketing and communications for US Lacrosse. “We’re excited to continue working with them and are grateful for their support of our mission.”

“We’re proud to continue our partnership with US Lacrosse and the U.S. National Teams, and we’d like to commend them for supporting innovation in the sport of lacrosse” said Erin Hanson, Guardian CEO and co-founder.

In 2015, in an effort to address the greasing issue of lacrosse balls, Guardian Sports re-engineered the lacrosse ball and introduced the Made in the USA Pearl X, formerly known as “The Pearl”, a game ball that doesn’t grease or harden over time due to its urethane composition.

The team expanded the Pearl line in 2018 by creating another USA made ball – Pearl NX.  The Pearl NX no-bounce practice lacrosse ball dies upon impact and is perfect for indoor play and practicing on hard surfaces with less bounce and rebound.  Pearl NX balls are the same size, weight, and hardness as Pearl X official game balls, so players can practice without the bounce of a standard ball without sacrificing the weight and feel. 

In 2019, Pearl lacrosse continued their innovation by introducing Pearl LT, the first SEI certified textured lacrosse ball that meets NOCSAE/NFHS/NCAA standards for game play.  Pearl LT is the latest innovation to bring a new look to the standard lacrosse ball. Pearl LT’s slight texture prolongs its grip and delays the effects of greasing.

As part of the agreement, Guardian balls will be used at all US Lacrosse competitions.
