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, coverage of 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 the jersey doesn't feel tight. Four different fabrics keep you dry while covering temperatures ranging 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," but the Endurance Pro Jersey really is master of all.
