Castelli Sinergia 2 Full-Zip Long-Sleeve Jersey - Women's Bordeaux/Brilliant Pink, L

Thermal jerseys are best when they're versatile, that's why Castelli keeps the Sinergia 2 streamlined for the perfect layering when things get cold. It offers just enough thermal warmth for chilled spring starts and cool fall evenings, but a sleek fit that's ideal under a jacket when the mercury dips way down.
