What Our Gearhead® Experts Are Saying:
"I grabbed this for a ride that started chilly but was supposed to warm up fast, and it turned out to be exactly the right call. It packed down small enough to stuff behind my saddle once the sun came out, and the high collar kept the wind off my neck on the way there."
The first ten minutes of a ride are almost always the coldest, and Castelli built the Transition Air Jacket to solve just that window without overcommitting to a heavier layer. We love throwing this on over a jersey for the rollout, trusting the microfiber nylon to block the wind while the fit stays close enough to disappear once we're moving.
A high collar keeps the draft off the neck on the way out of the driveway, and elasticated cuffs and waist keep everything sealed and tidy without a single loose edge. It's the kind of jacket that earns its spot in a pocket on nearly every ride, ready the moment the wind picks up.

Frequently Asked Questions
How should I size the Castelli Transition Air Jacket for women over my cycling kit?
Its tailored, women-specific cut is designed to sit close over a cycling jersey or light base layer, not over bulky outdoor layers. Use Castelli’s women’s size chart and your body measurements to choose a fit that allows your usual ride layers underneath.When is the Castelli Transition Air Jacket most useful on a ride?
It’s a lightweight layer for cool, breezy rides, early starts, short descents, and coffee stops. The listed comfort range is 10°C–18°C (50°F–64°F); it provides little insulation, so pair it with a warmer jersey or thermal layer as conditions cool.How does the Castelli Transition Air Jacket compare with a heavier cycling jacket?
This jacket prioritizes a light, packable layer and resistance to moving air rather than substantial insulation. Choose it for mild-to-cool rides and changing conditions; for sustained heavy rain or freezing weather, a waterproof or insulated jacket is a better match.How should I layer and use the Castelli Transition Air Jacket on the bike?
Wear it over a cycling jersey or light base layer, then use its top- and bottom-opening zipper to adjust access and airflow during the ride. The elasticated waistband helps keep the jacket settled against your cycling kit.How do I care for the Castelli Transition Air Jacket?
Close the zipper, turn the jacket inside out, and wash it at no more than 30°C (86°F) with mild detergent. Skip fabric softener and bleach, and hang or lay it flat to dry.
