The Puro 4 is a mid-weight Castelli jersey for cooler spring and autumn rides. A soft 3D knit made in Italy traps a little air for warmth, and the high-stretch fabric gives a close, tailored fit without feeling tight.
Reflective details on the shoulders and pocket add visibility, and pairing it with a warmer base layer extends its range into colder days.
