“As ambitions and expectations for TGR Haas F1 Team grow significantly, we’re delighted to partner with Castore to present this elevated merchandise experience for our fans,” team principal Ayao Komatsu said in a press release.
“As a name that has quickly become synonymous within our sport, Castore understands our need for agility and quality when providing the best to our team, and as a global brand, we’re excited to bring a greater offering via a first-class retail experience to our supporters.”
Tom Beahon, co-founder of Castore, added: “Our partnership with TGR Haas F1 Team continues the exciting momentum we’ve built in Formula 1.
“TGR Haas F1 Team represents another world-class organisation that shares our commitment to innovation and high performance. We’re proud to support the team with technically advanced apparel and to create elevated fanwear collections that bring supporters even closer to the sport. Together, we’re building on a powerful foundation as we enter this next chapter in Castore’s F1 journey.”
The British sportswear brand first signed to be McLaren's official team apparel and sportswear partner for the start of the 2022 season, with the organisation's branding being found on the teamwear and race suits. In 2023, it joined Red Bull, and two years later it joined Alpine with a multi-year deal. It has not been confirmed whether these existing partnerships will be altered at all.
2026 brings another huge change to Haas, with it reintroducing itself as TGR Haas F1 team after it successfully partnered with Toyota in 2024. TGR, standing for Toyota Gazoo Racing, replaces MoneyGram as its title sponsor.
