Castelli Women’s Sinergia Full-Zip Jersey – 2021

Simple with a Twist

Most of us use long-sleeve jerseys for a few days in the spring and fall, then extend their range with a vest in cooler weather, then pull them back out for insulation duty under a jacket in extreme cold. So a thermal jersey shouldn’t be too bulky or complicated, yet you don’t want boring. We built this with all the essential features like great fabric and fit, perfect pockets and our lightweight easy-sliding YKK Vision zipper. When you do wear it on its own, the small inserts in the chest and above the pockets give it an extra visual touch, and they happen to be reflective should you extend your ride to evening.

• Warmer fabric
• Iridescent reflective inserts on front and back
• 3 rear pockets
• Lightweight YKK Vision easy-sliding zipper
