Castelli has signed a nine-season agreement to supply race jerseys and apparel for the Tour de France and other ASO-organized professional road races. This multi-year partnership marks the return of the brand to the race, having previously supplied jerseys in the 1980s and 1990s.
Why it matters
The collaboration aims to standardize apparel technology across professional road racing while providing the manufacturer with significant global exposure. By supplying both men’s and women’s classification leaders, the brand seeks to maintain high technical standards for performance clothing.
The partnership follows 18 months of negotiations and will cover up to nine seasons of professional racing, including the Tour de France. Details regarding the exact implementation of specialized apparel for all future men's and women's event stages remain under development.

Health Landscape
Professional cycling continues to evolve toward highly specialized, condition-specific apparel to improve rider thermal regulation and comfort. This integration marks a broader shift in integrating advanced garment technology as a core component of elite athlete performance standards.
While this agreement focuses on professional athletes, it highlights the importance of selecting appropriate clothing weights and materials for high-intensity outdoor activity. Discuss with a coach or sports medicine expert how specialized layering can better regulate your body temperature during training.
The takeaway
The partnership reinforces the necessity of using weather-appropriate technical gear to maintain peak performance during endurance activities. Regularly evaluate your own training kit for proper moisture-wicking and insulation based on the specific environmental conditions of your workout.
