Designed for the rigors of commuting in all weather, this jacket keeps everything out while fitting over your office attire, but where it really shines, quite literally, is with the allover reflectivity that lights up at night yet is practically unnoticeable during the day.
- Castelli-exclusive 3-layer allover reflex fabric with 20,000 mm water column waterproofing and 20,000 MVTR breathability
- Taped seams for fully waterproof construction
- Cut to fit over normal clothes, longer in front and back for extra coverage
- No-sew bottom hem for very clean look
- No-sew external zipper flap
- Inner gaiter can be closed to seal out drafts or left open for ventilation
- Velcro wrist closure to effectively seal against gloves
This is the Castelli of commute jackets, made to deliver maximum function on the bike and then look great when you get to work.
We wanted a jacket that provides maximum visibility during those night commutes but doesn't look ridiculous with all kinds of silver reflective bands and strips when you get to the office. We applied a nearly unnoticeable reflective print on the entire surface of the jacket. You don't really see it when you're riding in the daytime or wearing the jacket off the bike, but at night the jacket reflects a distinctive pattern to get you noticed.
We didn't stop at the reflectivity. The 20,000 mm water column means no water is coming through, ever. And the 20,000 MVTR breathability means that a good amount of moisture will escape. But it's the ventilation details that make this jacket stand out: there's a gaiter at the waist that you can close to seal out the wind or leave open to let some air come in from the bottom to keep you cooler. This inner gaiter allows us to make a jacket that hangs straight at the bottom - a much cleaner and more refined look than a jacket with wrinkles from an internal elastic.

How to Measure
- Chest: measure horizontally under the arms around the fullest part of the chest.
- Waist: measure horizontally around the natural waistline, keeping the tape slightly loose.
- Hips: measure horizontally around the fullest part of the hips with feet together.
- Inside leg: measure a well-fitting pair of trousers from the crotch seam to the ankle.
- Hand circumference: measure around the hand using a tape measure or a piece of string and a ruler.
- Bra: measure bust at the fullest point and underbust directly below the bust.
Fit: Castelli specialises in performance cycling apparel and many garments have a close-to-body fit. The manufacturer's general rule is to choose the larger size when your measurements fall between two sizes. Product-specific fit guidance always takes priority.
