Castelli Squadra Stretch Jacket

This is a modern interpretation of the wind shell jacket, the one you keep in your pocket for a long descent or put on for the first hour of the ride until the day warms up. That jacket used to be a simple affair — a nylon shell — but the lack of stretch meant that it had to be cut on the generous side to fit all body shapes, both on and off the bike. |We've completely reimagined what the shell jacket should be and how it's constructed. We've added panels on the sides and the sleeves in a very high-stretch yet tightly knit fabric that allows us to give the jacket a modern, close-to-body fit for aero gains on any terrain, and it actually keeps more heat in than a jacket that's flapping about. We've kept it very compact so that it can pack away into minimal space in a jersey pocket.|The stretch panels are treated for water repellency, which will help in a light mist, but this is not meant to be a true rain jacket.

The Squadra Stretch shell keeps the wind off on cool-weather rides or long descents, while the stretch panels keep the jacket fitting close to body and eliminate flapping fabric.
