What Our Gearhead(R) Experts Are Saying:"I've had this in rotation through a whole fall of cooler morning rides, and it just quietly does its job every time. The zipper glides easy when I need to vent on a climb, and the rear pockets hold everything I need without ever feeling crowded."Fall and spring riding don't need anything flashy, just a layer that shows up and does the job right, and Castelli built the Sinergia 3 Full-Zip Long-Sleeve Jersey to be exactly that. We love reaching for this on a cool morning, knowing the warmer fabric will carry us through without a second thought about the temperature. A lightweight YKK Vislon zipper slides easy whenever a climb calls for venting, and three rear pockets with a gripper elastic waist keep gear secure and in place through every mile. This is the jersey that becomes the foundation of a shoulder season kit, dependable enough to reach for again and again.
