The Castelli Idro Pro really is the ultimate Gore-Tex® cycling jacket - Light, packable, highly breathable, durable, 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 chooses to) ride in any weather conditions. When GORE-TEX® introduced SHAKEDRY™ technology two seasons ago, Castelli immediately saw the opportunity to make waterproof jackets lighter than ever. And then when they tested it they realized that they where also able to make them more breathable than ever. Now, thanks to Gore’s new Topo inserts and the Gore®/YKK® integrated zipper, Castelli has been able to bring a close fit and extreme packability to a jacket that’s fully protective for all-day riding in the rain. Designed with two external pockets so you don’t have to unzip to reach your jersey pockets because you still have to eat if it's raining. The Idro Pro also features a longer tail to shield you from the spray coming off your back wheel, a soft neck liner and with hidden reflectivity for safety. Compared to the Castelli Idro 2 jacket, this is more of a workhorse jacket. It’s made for the rider who leaves his house for an all-day ride in the rain, for the rider whose jacket is a necessity and not a piece that stays in a pocket until it’s needed.
