The Perfect Addition To Your Fall & Spring Kits

Layer like you mean it with a jersey designed for intermittent temperatures. The Castelli Sinergia 2 is the perfect foundation thermal jersey for fall and spring riding, with additional features designed to perform.

A thermal jersey shouldn't be too bulky or complicated, yet you don't want boring. The Sinergia 2 uses warmer fabric for durable comfort mile after mile, with the breathability you need for those full sends. This jersey has all the essential features, like 3 drop-pockets, a Castelli stripe logo, and an easy-sliding YKK® Vislon® zipper.

Most cyclists use long-sleeve jerseys for a few days in the spring and fall, then use a vest in cooler weather, and finally for insulation under a jacket in extreme cold. The Sinergia 2 is perfect for any layering application, with a thin yet comfortable base that fits under a jacket while reflective piping keeps you visible when worn as-is.


  • Warmer fabric for comfort and breathability
  • Castelli stripe logo across upper chest
  • Lightweight YKK® Vislon® easy-sliding zipper
  • Three rear pockets with drop-pocket construction
  • Reflective piping at back enhances visibility
