Long-sleeve jersey designed to offer a precise balance between lightness, aerodynamics, and breathability, making it an ideal option for cyclists seeking maximum performance in transitional seasons or on rides with temperature variations. Its snug fit adapts precisely to the body, reducing excess fabric and improving efficiency on the bike. The garment's structure has been conceived to optimize airflow, channeling it toward the lower back and promoting better aerodynamics in motion. This new evolution incorporates an aero fabric on the sleeves, with a linear structure and zigzag weave, which gives a modern and sophisticated aesthetic, as well as improving aerodynamic performance and comfort during exertion. The elimination of classic cuffs in favor of a raw-cut sleeve finish offers a cleaner, lighter, and more ergonomic feel. This solution reduces pressure points, improves the fit on the arm, and reinforces the feeling of freedom of movement. The same technical fabric is also applied to the rear pockets, bringing aesthetic continuity, greater lightness, and a more precise integration of the whole. Its construction maintains the functionality needed for long rides, without compromising the garment's aerodynamic line. Its versatility makes it an ideal option for both intensive training sessions and prolonged rides with temperature changes, offering light protection, breathability, and performance in temperate conditions.
