Soudal/Quick Step Climber's A/C SS Jersey - Men's

What Our Gearhead® Experts Are Saying:

"This is one of the lightest, most breathable jerseys I have worn in a summer race. The Flusso 3D front and StradaPro 3D back work together to move sweat out fast, and the airflow shoulder construction makes a noticeable difference when you are deep in a long effort on a hot day. My go-to pick for summer racing and high-intensity training when the temperature is not doing you any favors."

The Castelli Soudal Quick Step Climber's A/C SS Jersey starts from a performance problem that every serious climber knows: sustained high-output efforts in extreme heat generate more sweat than most fabrics can move, and any buildup between skin and kit translates directly into discomfort and lost watts. Castelli engineered this jersey from the ground up to solve that equation, using CFD analysis to drive every fabric placement and seam decision so that airflow and moisture management are optimized across the entire surface of the garment rather than as an afterthought.

The dual-fabric construction is where that engineering shows up in practice. Flusso 3D across the front panels delivers structured ventilation precisely where solar exposure is highest and airflow is most needed during road racing and long alpine efforts. StradaPro 3D on the back panel is engineered to pull sweat away from the skin at speed, preventing the saturation buildup that slows heat transfer and adds perceived weight mid-ride. Airflow shoulder construction extends active cooling across the upper body through the kind of sustained threshold efforts that define competition in warm conditions. A form-fitting race cut reduces aerodynamic drag across the torso, and elbow-length raw-cut sleeves carry that aero advantage through the arms without any excess fabric. The full-length YKK Vislon zipper handles ventilation adjustments on descents and false flats, and the elastic waist keeps rear pockets stable and accessible under load.

With a UPF 13 rating, this jersey provides baseline sun protection for long days in exposed conditions. It is built specifically for riders targeting hot-weather climbing performance, summer criteriums, and high-intensity training blocks where thermal regulation is as important as power output.
