Gregarius Pro QLAB Jersey - Women's

What Our Gearhead® Experts Are Saying:

"This is the one I point to for truly hot rides. The airflow is immediate, the fabric dries incredibly fast, and the jersey never feels heavy even when the effort is high. It’s clearly built from real heat data, not guesswork."

Riding in extreme heat demands more than lightweight fabric—it requires intelligent airflow. The Gregarius Pro QLAB Jersey from Q36.5 is built using real-world thermal mapping from the brand’s research lab, translating heat data into targeted ventilation and moisture control for high-temperature riding.

An almost imperceptible 3D fabric across the torso creates a micro air barrier that accelerates moisture transfer, while a honeycomb mesh back panel drives a push–pull effect to move sweat outward for rapid evaporation. Raglan sleeves use a ribbed aerodynamic fabric that follows arm curvature, and mesh rear pockets reduce bulk while maintaining airflow. The result is a jersey designed to stay cool, light, and stable when conditions are at their most demanding.
