The Castelli Climbers 3.0 SS Jersey is designed to be light, dry and fast. Racing in the Alps in July may only be for a select few, but the products that come from these experiences benefit the rest of us. Castelli made the Castelli Climbers 3.0 SS Jersey with Team Ineos, 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 quicker drying. By using the same patterning as the Castelli Aero Race Jersey, they made sure you get maximum aerodynamics as well. You'll love the soft stretch and great fit of this jersey, and you'll appreciate how it keeps you cool even on the hottest days. This jersey can also be used like the pro riders do; worn on wet days because it doesn't soak up any moisture. Another excellent feature is that the fabric on the back of this jersey blocks more than 90 percent of UV rays.
