Castore becomes Haas F1 Team’s official kit partner amid TGR rebrand for 2026 season

The Haas F1 team has confirmed a retail partnership with Castore, with the company supplying its official kit going into the 2026 Formula 1 season.

Announcing the new partner on social media, the team said: "Welcoming Castore to the team as our Official Kit and Retail Partner.

"Engineered for the demands of Formula 1, this new partnership will see Castore design and supply all on-track and off-track performance apparel for the team, replica teamwear and a series of dedicated fanwear collections."

“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.
