JERSEY CLIMBER'S 4.0 CASTELLI

July races in the Alps are reserved for a select few, but the products resulting from this experience are perfect for everyone. We designed this jersey for hot days in the high mountains, based on feedback from professionals. They wanted a jersey that would keep them cool in hot weather without compromising aerodynamics. The Climber's 4.0 Jersey features the same CF seam placement as our Aero Race 7 Jersey, but it's made from the most aerodynamic 3D mesh fabrics for optimal cooling. These fabrics are also incredibly soft and stretchy, giving this jersey a comfortable fit—essential for intense days in the mountains. And since this jersey is designed for use in the sun, we've also ensured that the fabric blocks 90% of UV rays on the back.
