Castelli Climber's 4.0 Jersey

Created for the hottest days when aerodynamics still matter. This jersey allows ample airflow, is quick to dry, and blocks more than 90% of UV rays on your back. A great choice for long summer rides or hot lunchtime rides in the middle of summer — or just add a base layer and it becomes a great three-season jersey.
