Castelli Flight Jacket Air

Our lightest, fastest, and most breathable jacket is great for high-intensity riding or for maintaining the right body temperature in cool conditions. It features Polartec® Alpha® insulation without a membrane.

Technical Specs:

• Nano Flex Light fabric keeps out most of the riding wind, while the lack of a membrane ensures maximum breathability.
• Polartec® Alpha® active insulation on the chest, sleeves, and upper back provides extra warmth.
• Concealed YKK® Vislon® zipper prevents wind from entering.
• Stretch cuffs easily tuck into gloves or can cover glove cuffs to keep the cold out.
• Body-hugging fit.
• Three back pockets.
• Water-repellent finish.
• Reflective details on the back.

This jacket is ideal for fast rides on days that are too warm for a jacket but too cold for a jersey. Traditionally, you might have used a vest and arm warmers on those days, but this jacket performs better.

Instead of completely blocking the wind from your torso, the stretch fabric is minimally permeable. It keeps enough air out to prevent freezing while allowing enough through to keep you drier. Along with the shell, featherweight Polartec® Alpha® insulation provides essential warmth in key areas without sacrificing breathability.

The cut is close to the body, making it our most aerodynamic jacket. While aerodynamics may not be necessary in winter, we believe in the "Fast is Fun" principle. The close fit also makes the jacket warmer than minimalist materials would usually allow.

Additional features are strictly rider-oriented: The smooth-running YKK® Vislon® zipper allows for easy one-handed ventilation. Three back pockets offer ample space for everything you need on long rides. The jacket is cut short, ensuring it is not bulky in the front or back. Reflective details enhance visibility, and the outer material is water-repellent to keep out splashes and light showers.
