Castelli Sfida 2 Jersey FZ

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 doesn't flap.

• Coated ripstop nylon on the front, back, and sleeves to keep out the wind
• Close-knit stretch inserts on the sides and sleeves provide a perfect fit
• High collar to keep drafts at bay
• Reflective accents on the chest and lower back for visibility in low light conditions

This is a modern interpretation of the wind jacket that you keep in your jersey pocket for a long descent or wear during the first hour of your ride until it warms up. Such jackets used to be a simple affair—a nylon shell—but the lack of elasticity meant they had to be cut 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 added inserts on the sides and sleeves made from a very elastic yet tightly knit material, allowing us to give the jacket a modern, close-to-body fit to achieve aerodynamic gains on any terrain. And it actually retains more warmth than a jacket that flaps around. We kept it very compact, so it takes up minimal space in a jersey pocket. The stretch inserts are treated to be water-repellent, which helps in light mist, but it is not intended to be a true rain jacket.
