What Our Gearhead(R) Experts Are Saying: "This is the one for hard days. The fit is aggressive, the sleeves feel fast, and everything stays perfectly in place when the pace is high. It's clearly designed for racing, not just styled to look that way."When the focus is speed, every detail needs to disappear. The Gregarius Pro Collar Fade Jersey from Q36. 5 is engineered as the brand's most aerodynamic Gregarius jersey, tuned specifically for high-intensity riding and race-day efforts. It's designed to feel precise, stable, and uncompromising once the pace ramps up. Advanced body mapping integrates four distinct fabrics to manage airflow and fit across the torso and arms. A new ribbed aero sleeve fabric follows the natural curvature of the arms to reduce drag, while a proprietary raglan sleeve design supports a close, adaptive fit in the riding position. The result is a jersey that feels smooth, fast, and composed when riding at speed.
