What Our Gearhead(R) Experts Are Saying: "This vest has become my go-to for unpredictable spring rides. The AIRBLOCK fabric on the front really cuts the chill, while the VENTAMESH back keeps me from overheating on climbs. It packs small too, so I can stash it when the sun comes out." When conditions shift from cool to cold to damp, the Assos MILLE GTS Spring Fall 2/3 Vest S11 keeps our core protected without sacrificing breathability. Built with the new AIRBLOCK. 888 membrane on the front and sides, it shields against wind, water, and dropping temps, while the VENTAMESH rear panel promotes airflow and moisture management during long efforts. Designed with a low-profile fit, the vest layers easily over a jersey and tucks neatly into a pocket when the weather clears. By combining targeted protection with aggressive ventilation, it's a versatile piece for transitional rides, shoulder-season training, or chilly summer descents.
