Castelli Men's Goretex Idro 3 Jacket

This is a revolutionary jacket. To call it just a rain jacket would be an understatement, because while it’s amazing in the rain, we use it 95% of the time in dry conditions because it packs down so small that we always have it in our center pocket, ready to throw on. Perfect for tackling a long, cold descent, to layer up during a coffee break, or to keep a little warm while waiting for your training buddies to arrive. |We call it the Idro 3, and we’ll tell you what’s behind the name. Idro means “hydro” in Italian, or water. In this case, it keeps water out while letting sweat out, and it does both really well. We’ve never had this kind of performance before. The 3 in the name indicates that this is the third iteration. We’re close to the maximum performance possible in a shell jacket. The big innovation is at the back which features a high stretch panel in GORE-TEX® fabric that allows us to give the jacket a cut that will perfectly fit your body. (I.e. no fabric flaps in the wind, so you don't lose time on your comrades). The shape of the jacket seamlessly follows the contours of your silhouette even if you have well-filled pockets or if you have a bit of a belly. In addition to this stretch panel, we have carefully refined its cut, its construction finishes, its large reflective panels, and especially its wrist closures benefiting from new gaiters on the inside. |This jacket is ultra-complete in terms of features even if it will spend a lot of time in one of your pockets on days when it might rain or when on long descents in the Alps. It is lighter than many jerseys and only takes up half of a jersey pocket.|It has one small drawback: its fabric is so light that it is a little fragile, so take care of it. It will undoubtedly become one of the clothes you can no longer do without.
