Castelli ALII Run Jersey - Sleeveless - Women's

One foot in front of the other.

Tri training requires a pretty significant amount of organization, and whether you're planning a grueling brick day or are heading to the track to work on your leg speed, you don't want to add gear complications to the list of things you have to think about. Castelli's ALII Run Jersey for women exemplifies the kind of simplicity you need when you run.

Made with A-Vent polyester — an airy, open-weave microfiber — the jersey is incredibly breathable, so you can depend on it to help you stay cool while the sun beats down on you during track workouts. The fabric has inherent UPF 15 protection built-in, and Castelli employs a more relaxed fit on the scoop-neck design than what we usually from the brand, maximizing air flow and freedom of movement while you focus on splits, stride length, and your upcoming race.
