Named after Ali'i Drive, the finish line for the Ironman World Championships, the Alii run top was developed following a direct request from Timothy O'Donnell. Its sole aim is to keep you cool and comfortable during your run.
Using A-Vent fabric, Castelli has created a garment that's virtually weightless, with a loose cut that allows air to flow between it and the skin. It delivers excellent breathability but really shines when you can pour water over it at aid stations. With a UPF rating of 15, it blocks 93% of the sun's rays.
With roots dating back to 1876, Castelli has been at the forefront of fabric technology for almost 40 years. Alfredo Binda, Gino Bartali, Fausto Coppi, Jacques Anquetil and Louison Bobet were but a few of the legendary athletes clothed by Castelli. More recently, Bernard Hinault wore the first windproof jersey when he won Fleche Wallone. Castelli made that too!
