Phase Bike Jersey

The new full-zip Phase Jersey from Castelli was born in Italy and designed to warm the core while providing enough ventilation to prevent overheating. Best for temperatures in the mid 50-60s when worn solo (or into the single digits when layered under jackets) the interior is brushed for thermal warmth, but also highly rated in moisture management to ensure you stay comfortable as you ride. With flattering stretch side panels for mobility and 3 rear pockets that keep essentials in reach, it's feature packed to transition with you through the seasons. Athletic fit.
