CASTELLI Climber's 3.0 Men's Jersey Size:L Check out the Running PowerLIGHT, DRY AND FAST Racing in the Alps in July is for a select few, but the products that come out of that experience are absolutely amazing for the rest of us. We made this jersey for the rigors of pro racing in hot weather and in the high mountains. It's extremely lightweight and features open fabrics for additional airflow and quick drying. And by using the same patterning as the Aero Race Jersey, we make sure you get maximum aerodynamics as well.
