Castelli Idro W Jacket

A jacket that weighs less than a jersey? Real GORE-TEX, no less? And it packs up to fit in half a jersey pocket? And it's the most breathable GORE-TEX ever? Hard to believe, but it's all true. This jacket is a game changer. It's fully waterproof, as you expect from GORE-TEX, but with its exceptional breathability and packability, you'll find that it replaces all your other shell jackets. If your ride has the slightest chance of rain or a long descent or the possibility of temperatures dropping, this jacket will automatically go in your pocket. You can confidently do longer rides in conditions that you would have avoided with all your old jackets. While you can get this fabric from other brands, you can't get the Castelli fit, design and construction.
