After we've amassed all the super-mesh climbing kits and ideal layering systems for cold-weather adventure, we still need our favorite "go-to" jersey, like the all-new Castelli Passo. Capable of staring down nearly the full calendar, the Passo matches well for rides that range from 65-95 degrees F — and adding the appropriate base-layer may extend that range depending on your cold-weather tolerances. The form-fitting but comfortable ProSecco Micromesh contours to your riding position, whether you're fully in the drops at the front of the paceline or sat upright stretching out the sore back in the season-opening cyclocross race. Climbing-themed graphic piping — we see mountain-tops — courses over the entire jersey and looks fresh amid the pack of singular color-tones and large color-blocks of late.

Castelli extends the comfort and performance that define the Passo to the raw-cut sleeves, which feature no seams at the cuff to eliminate pinching and boost aerodynamics. Perforated side mesh panels enhance heat loss when the temperature climbs, and three rear pockets provide plenty of room to stash snacks and essentials for a long day in the saddle.
