The Prologo HD Long Sleeve FZ Jersey has a dual purpose: it gives your arms another layer on chilly mornings and can protect you from the summer sun’s harmful rays. Stratus fabric with Prosecco treatment is airy enough to wear in hot weather, and the mesh back insert allows for ventilation. Choose the white jersey for summer.
