In cycling jerseys made for cooler weather, as the temperature rises you could overheat. The Castelli Endurance Pro Jersey is for these long-distance rides with varying temperatures.

Sweat and body heat evaporate nearly instantly thanks to the Velocity dimpled and Air Mesh fabrics. The Multifilament fabric on back blocks 94% of UV rays. Store the food that fuels your pedaling legs for endurance rides in the large rear pockets that are easy to access. Nervato fabric at armholes and stretchy fabrics on front, back, and sides create an aerodynamic jersey; it’s fast enough for competitive rides and races, yet the jersey doesn’t feel too tight making them great for those extra long-distance rides. Comfort is even further improved with details like a flap over the zipper and sleeves with raw-cut edges that never bind nor constrict. Silicone gripper at waist secures the jersey while ensuring you feel comfortable leaned over your bike. A drop-pocket design keeps rear pockets from bouncing around when filled with energy bars, GUs, and the extra water bottle you need to keep hydrated on century length training rides.
