An impossibly perfect combination of being lightweight, packable, highly breathable waterproof and aero fitting make the Castelli Idro Pro 2 Rain Jacket hard to avoid if you are looking for an outer layer that will perform relentlessly in all conditions. Enjoy seeing water bead up and roll off with the impenetrable, yet highly breathable, Gore-Tex SHAKEDRY fabric and benefit further from Stretch Gore inserts at the elbow, shoulder and side panel that keeps the jacket fitted and secure. Two rear pockets mean there's no need to unzip to reach snacks and with a drop tail, your lower back will be well protected from road spray.
