What It Is

Created for the hottest days when aerodynamics still matter. This jersey allows ample airflow, is quick to dry, and blocks more than 90% of UV rays on your back. A great choice for long summer rides or hot lunchtime rides in the middle of summer — or just add a base layer and it becomes a great three-season jersey
Rosso Corsa

Our Rosso Corsa label is only applied to the highest-level products we make. Every thread and fiber, every curve and contour is obsessed about. Rosso Corsa represents a categorical breakthrough in cycling innovation and the meticulous craftsmanship you expect from Castelli’s performance-enhancing apparel.

Light. Dry. Fast.

Racing in the Alps in July is for a select few, but the products that come out of that experience are absolutely amazing for the rest of us. We made this jersey for hot days in the high mountains, based on direct feedback from the pros. They wanted a jersey to keep them cool on hot days without sacrificing aerodynamics. The Climber's 4.0 Jersey uses the same CFD-based seam construction as our Aero Race 7 Jersey, but we use the most aerodynamic 3D mesh fabrics we could find for optimal cooling. These fabrics also have a great soft and stretchy quality to them, giving this jersey a comfortable fit too, which you need for big days in the mountains. And since this jersey is meant to be used in the sun, we've also made sure the fabric on the back blocks 90% of UV rays.

Exceptional jersey for hot and humid weather

11/08/2024

Love this jersey a lot. Like how it snuggly fit. Saved me from heat at the south all the time. I had the first and second iteration of this climber jersey and can say only positive things about the #4.0.
5’9” 155 lb size M fits well (not a climber). If you like some freedom during the ride go a little up in the size.
