The National Lacrosse League, North America’s top league for box lacrosse, has signed a new agreement that makes Capelli Sport the Official Uniform of the League through 2029. Capelli replaces a deal with Castore.

Through the agreement, New York-based Capelli Sport will exclusively outfit all NLL franchises with on-floor jerseys and shorts, while also developing training and lifestyle collections. The agreement also supports fan experiences, including grassroots and community initiatives throughout NLL markets.

“Partnering with Capelli Sport at this stage of the National Lacrosse League’s growth is both strategic and symbolic,” said Brett Frood, commissioner of the NLL, which is set to celebrate its 40th anniversary during the 2026-27 season. “As a global, innovation‑driven team‑sport brand, Capelli Sport delivers the high‑performance quality and design our teams and athletes demand, while extending that same standard to our fans. Together, we are excited to outfit the League with best‑in‑class uniforms and replica jerseys that strengthen the bond between our players, our teams, and the broader lacrosse community.”

“The National Lacrosse League represents everything we look for in a partner: elite competition, passionate fanbases, and a league on a powerful growth trajectory,” said George Altirs, founder and CEO of Capelli Sport. “Partnering with the franchises in a true league-wide agreement allows us to fully leverage our vertically integrated global model to invest meaningfully in the future of professional lacrosse. We are proud to support the athletes, teams, and communities that define the NLL and to help shape the next chapter of the League’s evolution.”

The National Lacrosse League, based in Philadelphia, is comprised of 14 teams, including seven in the United States and seven in Canada.
