Q36.5 Gregarius Q36.5 Pro Cycling Team Vest At the centre of the Gregarius Hybrid Vest is Q36.5’s proprietary high-density knitted fabric, delivering membrane-level wind resistance while maintaining exceptional breathability and efficient moisture wicking. Unlike traditional windproof fabrics, this “natural windproofness” allows the vest to actively manage heat and moisture, helping to keep you comfortable when climbing hard, pushing through exposed roads or descending at speed. The body-mapped construction has been refined using wind-tunnel analysis to provide targeted protection where it is needed most. Extended thermal fabric across the back shields against cold airflow around the torso, while strategically placed mesh panels improve ventilation during harder efforts. With raw-cut arm openings and hem for a smooth, low-bulk fit, the Gregarius Q36.5 Pro Cycling Team Vest packs easily into a pocket, making it an essential layer for performance-focused cyclists.
