Four seasons. Two Constructors titles. One Drivers Champion. Multiple race programmes. And a partnership defined not just by kit, but by commitment. As 2025 draws to a close, we take a look back not with nostalgia, but with pride in what was built through precision, ambition and a shared belief in performance without compromise. 

This story is about a remarkable chapter in modern motorsport and the privilege of supporting a team that elevated itself across every series it touched. 

When Castore joined McLaren Racing in 2021, the Formula 1 team was beginning the climb back toward the sharp end of the grid. The year that changed everything arrived soon after. 

Austria 2023. A new floor. New sidepods. New bodywork. A full aerodynamic reimagining that shifted McLaren Racing from the midfield to the front runners. Every engineer felt the surge. Every fan saw the tide turn. For Castore, these moments mattered because preparation needed to keep pace with performance. Jackets engineered for the freezing mountain air of Spielberg. Breathable layers designed for long days on the pit wall. 

Japan 2023 brought the next breakthrough. A double podium. A first career trophy for Oscar Piastri. A statement that McLaren Racing’s rebuild was no longer potential, but progress. 

By 2024 the team was no longer rebuilding. They were redefining what was possible. Every upgrade and every hour in the garage carried a clear intention to move forward. The results validated that belief. When the team lifted the Constructors trophy in Abu Dhabi it marked not only a return to the front, but the completion of a journey shaped through detail, discipline and unity. Castore was honoured to support that rise with performance wear trusted in the most demanding environments. 

Momentum accelerated in 2025. One two finishes. Clarity of purpose. A home victory at Silverstone that captured everything McLaren Racing represents. A British driver. A British team. A moment that connected heritage, pride and performance in its purest form. Securing a second consecutive Constructors title with rounds to spare was the final expression of a culture built around marginal gains and accountability. 

Throughout these years Castore provided the layers that supported the effort. Waterproof protection for Spa and Zandvoort. Lightweight breathable kits for Singapore, Austin, Mexico City and Bahrain. Commemorative collections that marked iconic weekends from Monaco to championship celebrations. 

McLaren Racing is more than a Formula 1 Team. It is a racing collective that challenges limits across multiple disciplines. 

In IndyCar the speed increases and the margins become razor thin. The Arrow McLaren IndyCar team require kit that offered full mobility, fast drying performance and comfort for long hours in the heat. Castore is proud to support their push through relentless schedules and high-pressure environments. 

In Formula E the team carries its competitive spirit onto electric grids around the world. Extreme conditions demand apparel that can handle rapid temperature swings and the relentless rhythm of non-stop operations. Castore supports the team with lightweight layers built for constant movement in intense indoor environments. 

In Extreme E the demands shift again. Off road courses. Heavy terrain. Unpredictable climates. Castore deliver weather resistant protection and durable fabrics capable of enduring the elements that define this series. 

Across every series the mindset is the same. Prepare with intent. Perform with clarity. Improve with discipline. Castore stands alongside each team with apparel designed to reduce distraction and increase focus, regardless of the discipline or conditions. 

There are moments in sport that feel bigger than a season. Lando Norris becoming Drivers World Champion is one of them. A British driver. Leading a British team. Supported by a British performance brand. Three paths that began separately and converged into a defining moment. 

Lando’s campaign was built on control, intelligence and unshakeable pace. The year he shifted from contender to constant. The year every late move on the brakes, every measured defence and every inch perfect lap added another layer to a champion in the making. This title was not won in a single weekend. It was earned through years of craft, resilience and intent. 

To stand alongside him and alongside McLaren Racing through this rise is a privilege. From factory preparation to race day execution. From cold mornings in Europe to the heat of the Middle East. We have been proud to support a journey that reflects everything Castore stands for. 

A champion built through detail. A team built through unity. A moment built in Britain and shared with the world.
