It's a classic-looking performance jersey and a perfect match to the Premio short. - Lightweight 120 g 53/47 polyester/wool mix - Embroidered patch logos - Giro3 gripper elastic at waist - Metal Castelli zipper pull - 3-pocket drop-tail design

Finally, it features three main back pockets plus a zippered one to store all your snacks and essentials that are sure to keep you going all day. - Three standard pockets provide ample space for all your ride essentials. - Full-length front zipper to manage ventilation easily. - Fabric Content: MAIN: 85% Nylon, 15% Elastane - OTHER: 90% Polyester, 10% Elastane

Does gravel need a new dress code? maybe, but with fat tires and big-tubed bikes with bags on them, an aero jersey just doesn't look right. But why should you give up performance and comfort? that's the concept behind this jersey: all the performance of Castelli's best jerseys except the aerodynamics. First, we created a new fabric with leading Italian knitter Borgini. The lightweight fabric has a small horizontal stripe and a gorgeous soft hand. It maintains outstanding moisture management and ample horizontal stretch but has limited vertical stretch so your pockets don't sag. And it blocks 98% of uv rays. The jersey has a neutral fit to it: straighter in the body, extra space across the chest. Less drop from front to back. The design is clean and technical; even the chest stripe is embossed for tone-on-tone detailing. No more feeling self-conscious at your coffee stop. The jersey is full of thoughtful details, like a covered YKK front zipper, a fourth zippered key pocket, and bonded no-sew sleeve endings. - Interlock 115g 100% polyester fabric for excellent moisture management - Medium fit for comfort on the trail or road - Partially covered YKK Vislon zipper - 3 rear pockets with extra zippered security pocket - Embossed stripe across chest

An endurance cycling jersey with a streamlined fit, breathable textile, and frictionless raw-cut sleeves, re-engineered with lighter construction and less restriction. For the next evolution of our proven MILLE GT jersey, we opened the front of the collar and updated the fit across the chest and throat, relieving pressure for easier breathing and less restriction. The sleeves and collar feature a new material that shaves 15g (size medium) off the previous jersey's weight while retaining the highly elastic, wrapping fit and active moisture management. The new bonded hem and zipper reduce friction between layers and rippling across the stomach while in the riding position. - 73%PL 15%PA 12%EA

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 Pro Jersey really is master of all. - Endurance and all-around jersey with mix of aerodynamics, comfort, and convenience - Velocity dimpled fabric on front and shoulders for faster drying - Air mesh sleeves with raw-cut sleeve ending - Multifilament fabric on back blocks 94% of UV rays - Nervato fabric at armholes for improved aerodynamics
