Castelli Espresso 2 Womens Jersey The jersey you keep reaching for, ride after ride. Air_O Stretch fabric is the foundation of the Espresso 2. Castelli engineered it with high horizontal elasticity for a close, comfortable fit and limited vertical stretch to keep the back pockets stable and load-ready. The open-knit construction at 105g/m^2 stays genuinely airy, and the UPF 30 rating blocks 97% of UV - useful on long summer days when sun exposure adds up. The Version 2 update sharpens the fit, shortens the front panel slightly, and tightens up the pocket construction so a full load of food and gear sits without sagging. It works for a training ride, a gran fondo, or a casual coffee spin - the fit and finish hold up across all of them.
