Discover Castelli’s new summer collection at Escapa. The Castelli Climbers 4.0 Short-Sleeve Jersey is perfect for hot days thanks to its optimal airflow, which allows sweat to dry quickly and blocks more than 90% of UV rays.
This jersey is ideal for hot days, based on direct feedback from professionals. They wanted a jersey that would keep them cool on hot days without sacrificing aerodynamic performance.
The Climbers 4.0 jersey uses the same seam structure—based on CFD analysis—as our Aero Race 7 jersey, but we’ve also incorporated 3D mesh fabrics with superior aerodynamic performance that provide enhanced cooling. These high-quality fabrics are also extremely soft and stretchy, giving this jersey the comfortable fit you need for your extraordinary days in the mountains. Furthermore, knowing that this jersey will be worn in the sun, we’ve ensured that the fabric on the back blocks 90% of UV rays.
