Flusso 2 Limited Edition Jersey - Men's

What Our Gearhead® Experts Are Saying:

"Prosecco GT is one of Castelli's go-to warm-weather fabrics for good reason — it's genuinely lightweight and moves moisture efficiently rather than just sitting on the skin and hoping for evaporation. The mesh side panels are positioned where the torso generates the most heat under load, so the ventilation is intentional rather than decorative. The semi-fitted cut is the right call for a training jersey at this price; it's performance-oriented without being punishing if your body doesn't match a pure race fit. Size up from your normal — this jersey runs small, and the fit suffers if you don't."

Heat management in cycling jerseys comes down to two things: how quickly the fabric moves moisture away from the skin and how much airflow the construction allows at the body's highest heat-output zones. The Castelli Flusso 2 Limited Edition Jersey addresses both directly, pairing Prosecco GT fabric with strategically placed mesh side panels for a jersey built specifically around warm-weather riding performance.

Prosecco GT is a 100% polyester fabric engineered for low weight and active moisture wicking — it pulls sweat away from the skin rather than absorbing it, allowing evaporative cooling to work efficiently even during sustained high-output efforts on long climbs in heat. The fabric dries quickly enough that the jersey doesn't become progressively heavier over the course of a long ride, which is the primary failure point of heavier summer fabrics. The mesh side panels — constructed from a 94% polyester, 6% elastane blend — provide stretch where the torso expands during deep breathing under load, while opening direct airflow channels at the flanks where body heat concentrates during hard efforts.

The semi-fitted cut sits close to the body without the compression of a pure race fit, making it accessible for a wider range of body types and more comfortable across training-length efforts where a skintight fit becomes fatiguing over time. Three rear pockets provide standard functional storage for nutrition and essentials, and high-visibility strips improve rider visibility during early morning or late evening rides when light conditions are variable. The full-length zip allows ventilation to be adjusted on the fly — fully open on climbs, partially closed on descents.

One important fit note: the Flusso 2 Limited Edition Jersey runs small relative to Castelli's standard sizing. Sizing up from a rider's usual size is consistently the recommendation for the best fit and most comfortable wear across a full ride.
