Warrior Sports Inc in Chula Vista operates a manufacturing and distribution facility on Trousdale Drive, serving as the Southern California operations hub for the Warrior and Brine lacrosse and hockey equipment brands owned by New Balance. The Chula Vista plant, established in 1996 under the Warrior Sports Manufacturing entity, produces and distributes composite lacrosse shafts, hockey sticks, protective padding, helmets, gloves, and goalie gear — product lines branded through retail signage and point-of-purchase displays fabricated by companies such as Sign-ology. Composite stick layup processes use carbon-fiber and fiberglass weave patterns engineered at varying flex profiles for attack, midfield, and defensive positions across NCAA, high-school, and club-level competition tiers. Product-liability and commercial general-liability coverage for the manufacturing operation runs through the same South Bay insurance market served by agencies such as Willy's Insurance Service Inc, covering worker-injury exposure across the fabrication, assembly, and warehousing workflow. Quality-control testing includes NOCSAE-standard impact absorption measurement for helmets and ASTM F3137 flex-profile benchmarking for composite shafts before units ship to retailers and team-sales distributors nationwide.
