TGR Haas F1 Team has appointed performance sportswear brand Castore as its Official Kit and Retail Partner in a multi-year collaboration that will begin with the team’s rebranded entry.

Under the agreement, Castore will design and supply both on-track and off-track apparel for team personnel, including performance apparel for drivers and engineers.

The partnership will also produce replica teamwear and a range of dedicated fanwear collections, including special releases linked to the Japanese Grand Prix and U.S.-focused designs.

“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,” said Ayao Komatsu, Haas Team Principal.

“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.”

Castore co-founder Tom Beahon said the expanded presence in Formula 1 reflects the brand’s growing portfolio within the sport. “TGR Haas F1 Team represents another world-class organisation that shares our commitment to innovation and high performance,” he said.

“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.”

Castore already has a significant footprint in Formula 1. It supplies official team apparel for the Oracle Red Bull Racing, a long-term relationship that has been extended to become one of the largest apparel agreements in the sport.

The brand also partners with the BWT Alpine F1 Team as its official team kit supplier and has previously supplied apparel to other teams.

The expanded collaboration further consolidates Castore’s position as a leading technical apparel partner in elite motorsport, supporting both performance and commercial retail initiatives as it continues to grow its portfolio around the world.
