The Castelli W Espresso 2 Jersey refines the go-to jersey design with Air_O Stretch fabric that balances a close-to-body fit with exceptional breathability, moisture management, and aerodynamics. Updated with a shorter front fit, this version delivers improved comfort without feeling constrictive, while raw-cut sleeve endings eliminate pressure points. Four rear pockets—including three standard pockets and a fourth zippered security pocket—keep essentials organized and accessible on every ride. UPF 30 sun protection, a full-length YKK® Vislon® zipper with easy-pull tab, and silicone-backed elastic at the waist ensure this jersey stays secure and functional whether you're racing or logging long training miles.
