What Our Gearhead® Experts Are Saying:
"I keep this jacket in my back pocket for any ride where the forecast might shift, and it packs down small enough that I barely notice it's there. The high collar blocked drafts on a windy descent without ever feeling stifling once I picked up the pace."
Some rides need one more layer, not a heavy one, just something quick to throw on when the wind picks up, and Castelli built the Transition Air Jacket for exactly that moment. We love how the lightweight microfiber nylon blocks wind almost effortlessly while still breathing enough to avoid overheating once the effort climbs.
An ergonomic cut keeps the fit clean without restricting movement, while a high collar shuts out drafts at the neck. Elasticated cuffs and waist finish the look with a secure, no-fuss fit that works as easily off the bike as it does on it.
