Sidekick Boxing, a leading combat sports equipment brand, has been making waves in the fight world by sponsoring some of the best strikers competing in ONE Championship. After previously backing Jonathan Haggerty for two world title fights, the brand has now partnered with rising star George Jarvis—while actively looking to expand its roster of sponsored athletes.
Jonathan Haggerty: A Champion’s Journey
Jonathan Haggerty is one of the most exciting strikers in combat sports today. The English Muay Thai specialist is known for his lightning-fast combinations, powerful elbows, and relentless aggression inside the ring. Haggerty first captured the ONE Flyweight Muay Thai World Championship with a stunning victory over Sam-A Gaiyanghadao, showcasing his ability to compete against the sport’s elite.
Sidekick Boxing was proud to support Haggerty in two of his world title fights, recognizing his dedication, skill, and warrior spirit. His performances on the global stage have helped elevate British Muay Thai and inspire a new generation of fighters.
George Jarvis: The New Generation
Now, Sidekick Boxing has turned its attention to another British striking talent—George Jarvis. A highly skilled and technical fighter, Jarvis has been making a name for himself with his sharp striking and strategic fight IQ. His rise through the ranks has not gone unnoticed, and with Sidekick Boxing in his corner, he continues to push toward greatness.
As Jarvis competes under the ONE Championship banner, he represents the next generation of British fighters looking to dominate on the world stage. His partnership with Sidekick Boxing aligns perfectly with the brand’s mission of supporting top-tier athletes in their pursuit of excellence.
