Just one ride and it’ll change your idea of how good a thermal jersey can be.

Castelli re-engineered the Garmin thermal jersey surprised everyone a bit. The Garmin riders raved about the jersey, and we even picked it out being used in races last spring. It’s a PERFECTION SIMPLIFIED kind of garment: Warmer fabric on the body to keep your core warm, Warmer X-Stretch on the sleeves to eliminate flapping fabric, a YKK® Vislon zipper for easy up/down.
