This product comes into the Castelli lineup as a direct request from Timothy O’Donnell when he wanted to do better than his fifth place Kona finish. The objective is clear: keep cool and comfortable during the run. We took our insanely light and ventilated A-Vent fabric and gave it a loosish cut to allow maximum airflow between the top and the body. The top weighs next to nothing but covers a wide range of conditions: the fabric is excellent at keeping you dry when you want it too but really shines when you need cooling and can pour water over it at the aid stations.
Super lightweight to keep you cool on the move. The Castelli T.O. ALII Run Top is perfect for hot weather racing. The looser fit allows more ventilation between the top and the body, which is further helped by the open-mesh knit. The UPF 15 rating blocks 93% of UV rays, so you’re protected from sun damage.
