What Our Gearhead® Experts Are Saying:
"I've had this in rotation for group rides all season since it packs down to almost nothing but still earns its spot on the bike. It handled everything from a chilly rollout to a quick stop at the café afterward without ever feeling out of place."
A good vest earns its keep by doing a lot with very little, and Castelli built the Transition Air Vest around that idea. We love how the microfiber nylon blocks wind the second it's needed, then folds down small enough to disappear into a pocket the moment it isn't.
The asymmetrical zip with its branded scorpion puller adds a small, considered detail to a piece that's otherwise all function, while an elasticated waist keeps the fit clean whether we're mid-ride or standing around after. It's the kind of layer that moves easily between a hard effort and a coffee stop without missing a beat.

Frequently Asked Questions
How should I size the Castelli Transition Air Vest - Men’s over a cycling jersey?
It has a slim, tailored fit and is listed in men’s sizes S–3XL. Choose based on your chest and waist measurements, allowing room for the jersey layers you plan to wear beneath it.What temperatures suit the Castelli Transition Air Vest for road cycling?
Castelli recommends the vest for 12–20°C (53–68°F), making it suited to cool, breezy rides and shoulder-season starts or descents. Below that range, pair it with warmer layers rather than relying on the vest for insulation.What does the Castelli Transition Air Vest’s 20D fabric offer?
The vest uses 20D 100% nylon microfiber, designed to block airflow while retaining air permeability. It has no conventional insulation, so it adds modest core warmth when layered over a jersey rather than replacing a thermal layer.How light and packable is the Castelli Transition Air Vest?
The vest weighs approximately 66 g in size M and packs into its own pocket. That makes it a practical layer to carry for changing wind during a road ride.How can I adjust airflow in the Castelli Transition Air Vest while riding?
The asymmetrical zip allows quick venting adjustments, while the high collar helps limit drafts at the neck. Its 20D nylon microfiber is designed to retain air permeability, and the elasticated waist helps keep the fit secure on the bike.
