Castelli quadra tretch W Jacket

The Squadra Stretch outer material blocks the wind during rides in cool weather or long descents, while the stretch inserts ensure that the jacket fits snugly to the body and does not flap.

• Coated ripstop nylon on the front, back, and sleeves to block the wind
• Closely knitted stretch inserts on the sides and sleeves provide a perfect fit
• High collar to keep drafts at bay
• Reflective details on the chest and lower back for visibility in low light conditions

This is a modern interpretation of the wind jacket that you carry in your jersey pocket for a long descent or wear during the first hour of your ride until it gets warmer. Such jackets used to be a simple affair—a nylon shell—but the lack of elasticity meant they had to be cut quite generously to fit all body shapes, both on the bike and before and after the ride. We have completely redefined what a wind jacket should be and how it is constructed. We have added inserts on the sides and sleeves made from a highly elastic yet closely knitted material, allowing us to give the jacket a modern, body-hugging fit to achieve aerodynamic gains on any terrain. And it actually retains more warmth than a jacket that flaps around. We have kept it very compact, so it takes up little space in a jersey pocket. The stretch inserts are treated to be water-repellent, which helps in light mist, but it is not intended as a true rain jacket.
