Why We Like The Castelli Climber's 4.0 Jersey

Built for hot summer days in the mountains, Castelli’s Climber's 4.0 Jersey keeps us cool without sacrificing speed with its lightweight fabrics and rapid cooling properties. This high-alpine-focused jersey features the same aerodynamic CFD-based seam construction as the Aero Race 7 jersey but with 3D mesh fabrics that keep us cool and comfortable as we ride through the summer heat.


  • A high-performance jersey built for hot summer days in the mountains
  • Built with aerodynamic 3D mesh fabrics for unmatched speed and cooling
  • The StradaPro 3D rear fabric blocks 90% of UV rays for protection against the sun
  • Elbow-length stretch sleeves with a raw-cut edge sit comfortably against the arm
  • Elastic at the waist keeps the jersey in place as we move in and out of the saddle
  • Three rear pockets keep our essentials closely within reach
  • Item #CSTZ7SY
