Castelli Squadra 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.

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.
