Jerseys/Tops (Short Sleeve)

What It Is Class-leading aerodynamics paired with all-day comfort. This jersey in engineered to save you watts while managing moisture and providing comfort for the longest rides. Aerodynamics, Comfort, and Style. When Castelli engineered the first aero jersey for road racing back in 2006, everyone thought we were crazy, even a few of the pro riders. Back then, aero was only for TTs. Performance clothing meant moisture management. And you could win the Tour de France with a baggy jersey that was little more than a polyester T-shirt with pockets on the back. Even our aerodynamic consultants expected limited, if any, gains, so we named the jersey the Split Second. In the end, the gains were pretty substantial, and we completely revolutionized the look of the pro peloton. We're now on the seventh major revision of that jersey, and we've found even more gains. Still heavily benefitting from CFD analysis of wake flow in the riding position for fabric and seam placement, along with pro rider feedback, this jersey is both fast and comfortable for long days in the saddle.

What It Is The ideal all-around jersey is great for endurance rides, offering comfort and convenience features, excellent moisture management, and Castelli's aerodynamic wizardry. Master of All If you had to choose one jersey to do it all, this would be the one. The name kind of says it all: Endurance. For your long rides, a jersey needs to be able to do it all, offering comfort, carrying capacity, a wide temperature range with sun protection, and good aerodynamics. This jersey checks all those boxes. The comfort comes from a close-to-body fit with stretchy fabrics so it doesn't feel tight. Four different fabrics keep you dry while covering every temperature range from mild to hot. And extra comfort comes from details like the flap behind the zipper to protect your neck and the stretch sleeves with raw-cut edges that never bind or constrict. The pockets feature Castelli's drop-pocket design, which places the pockets lower on the back for easier access. There's even a fourth zippered pocket for valuables. Your long rides and even your short rides will be faster with less effort because this jersey is also highly aerodynamic, especially through the sleeves and shoulders, which feature the same fabric used on several generations of our pro-level race jerseys. The old saying is jack of all trades, master of none. The Endurance Elite Jersey really is master of all.

What It Is Designed and engineered with an emphasis on comfort and performance, no matter what type of ride you are planning on today, the Espresso Jersey is the best choice. Your New Favorite Jersey When we set out to make this jersey, we wanted the jersey that we'd always reach for the second it was washed and dry after the last time we wore it. No matter if you normally wear an aero race-fit jersey or a more regular cut jersey, the Espresso will be your new favorite jersey. First, we focused on the fit and fabric of this jersey. We developed a fabric that would allow for a close-to-body fit without being constrictive or feeling tight. The fabric we developed also offers great breathability and moisture management, and as an added bonus, we found that the fabric tests well in the wind tunnel too! Next, we focused on the waist and pockets, so that you can load up the pockets when a long day is in store and nothing moves around. There is a fourth zippered security pocket to keep your valuable safe. Finally, we use a tried and trusted full-length YKK® Vislon® zipper. We're sure that this will be the jersey you always go to, no matter what the ride is that day, because Espresso is always a good idea.

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. 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.
