The Castelli Men's Idro Pro Jacket is lightweight, packable, highly breathable, durably waterproof, and aero fitting. This is the first piece that brings all those features together into a jacket made for the rider who has to (or choses to) ride in any weather conditions. When GORE-TEX® introduced SHAKEDRY™ technology two seasons ago, riders and designers alike immediately saw the opportunity to make waterproof jackets lighter than ever. And then Castelli tested it and realized that they were also able to make them more breathable than ever. Now, thanks to Gore’s new Topo inserts and the Gore®/YKK® integrated zipper, this jacket provides a close fit and extreme packability to be fully protective for all-day riding in the rain. With two external pockets, the Idro Pro adds easy-access to the essentials without having to unzip and reach for the jersey pockets. A longer tail to shields from the spray coming off the back wheel.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.
