Castelli Free Speed 2 Race Maglietta a maniche corte Donna, nero

The right race jersey for speed and comfort
Some triathletes choose long sleeves for the extra speed. Some for the comfort. Some for sun protection. This jersey gives you all three.

The aerodynamic speed is unmatched. It's what Castelli does best. Castelli has a year-round testing and development program with the Norwegian Technical University in Trondheim to make their race gear the slickest around.

The comfort is what comes from their expert pattern engineers and soft performance Italian fabrics. Castelli reduces the number of seams so that there is less chafing and less to bother you when you should be concentrating on pounding out the run.

Sun protection... well, you've trained untold hours for this day. Castelli focuses on speed, but they still manage to block 94% of UV rays with the back Velocity mesh fabric that doesn't compromise speed, comfort or breathability. You may want to add some sunscreen, but this fabric provides UPF 16 protection, which is a significant help. Your cotton T-shirt is probably UPF 8.

Take note of the well-thought-out details: Castelli's generous two pockets lie flat but hold a lot of gear and nutrition. The SnapLock fasteners clip to Castelli shorts to prevent the top from riding up during the swim or bike.

Rosso Corsa
Castelli's Rosso Corsa label is only applied to the highest-level products they 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-enhacing apparel.
